JACKINWORLD SURVEY #3
This Survey was held in October '97 over a period of about six days. A total of 1,208 responses were collected. Of the multiple-choice questions, fewer than 1% were not answered. If fewer than 1,200 people answered a given question, a "no answer" percentage is included with the results; otherwise, the percentages reflect only those who chose to answer the question.
Here is a list of the questions, followed by a breakdown of the responses:
1. Age

Average age | 20.9 | |
Low age | 11 | |
High age | 74 |
2. Location
(a) U.S. - Pacific/
......Rocky Mountains | 15.8% | |
(b) U.S. - Midwest | 21.5% | |
(c) U.S. - South | 18.5% |
(d) U.S. - Eastern Seaboard/

......Hispanic | 3.3% (average age: 19.3) |
(e) Middle Eastern/
......Semitic | 0.6% (average age: 18.7) | |
(f) Native American | 1.7% (average age: 18.0) | |
(g) Other | 2.3% (average age: 22.0) |
4. Religion

|
(a) not religious at all | 32.0% |
(b) raised religious, still accept
......religious teachings somewhat | 40.2% |
(c) have strong spiritual convictions
......associated with a major religion | 22.8% |
(d) have strong spiritual convictions not
......associated with a major religion | 5.0% |
Note: In the analyses of other questions in this Survey, a reference to "very religious readers" refers to those who answered (c) on this question.
5. Masturbation Frequency
Question: On the average, how many times per week do you masturbate to orgasm?
|
(a) Less than 1 | 1.2% | |
(b) 1 to 3 | 16.6% | |
(c) 4 to 6 | 33.6% | |
(d) 7 to 10 | 25.8% | |
(e) 11 to 14 | 12.8% | |
(f) 15 to 20 | 6.4% | |
(g) 21 to 30 | 2.9% | |
(h) more than 30 | 0.8% |
This works out to a rough average of 7.9 times per week.*
Breaking out this average by age:
|
• ages 11-13 | 10.8 times per week | |
• age 14 | 8.8 | |
• age 15 | 9.1 | |
• age 16 | 8.8 | |
• age 17 | 8.6 | |
• ages 18-21 | 7.5 | |
• ages 22-35 | 6.3 | |
• ages 36 and up | 5.3 |
Breaking out the overall average by ethnicity:
|
• African (black) | 5.6 times per week | |
• Asian/Pacific Islander | 7.8 | |
• European (white) | 8.1 | |
• Latin-American/Hispanic | 7.8 | |
• Middle Eastern/Semitic | 6.6 | |
• Native American | 6.5 |
Among very religious readers, the overall average is 7.7 times per week; among the non-religious, the average is 8.1.
|
Although there weren't enough responses by non-whites to make a definitive statistical analysis, it would appear white JackinWorld readers masturbate slightly more frequently than non-whites. Are white people the horniest folks on the planet, contrary to many racial stereotypes? Could be! (A larger sample is needed to test this further.) Also, religious readers masturbate slightly less frequently than non-religious readers (or at least report lower frequencies). Guilt may be a factor — see #18 below. |
*This figure, and those that follow, were calculated by assigning median values to responses (b) through (g), using 0.5 times per week for (a) and 35 times per week for (h), and averaging the resulting figures.
6. Masturbation Frequency Maximum
Queestion: What is the most number of times you've masturbated to orgasm in a 24-hour period?
|
(a) 1 | 1.2% | |
(b) 2 | 7.3% | |
(c) 3 or 4 | 46.6% | |
(d) 5 or 6 | 27.5% | |
(e) 7 to 10 | 13.8% | |
(f) more than 10 | 3.6% |
7. Masturbation Abstinence
Question: Not counting your childhood, what is the most number of days you've gone without masturbating? (Note: Masturbating on Monday and Thursday but not Tuesday or Wednesday would count as 2 days.)
|

(b) 1 | 2.5% | |
(c) 2 | 5.2% | |
(d) 3 or 4 | 19.2% | |

(f) 7 to 30 | 41.7% | |
(g) more than 30 | 8.0% |
8. Sexual Activity
Question: On the average, not counting mutual masturbation, how many times per month do you have sexual contact to orgasm with another person?
|
(a) rarely or never | 72.9% | |
(b) 1 to 4 | 16.0% | |
(c) 5 to 10 | 6.6% | |
(d) 11 to 20 | 2.7% | |
(e) more than 20 | 1.7% |
9. Bedroom-Sharing
Question: Most of the time, does somebody else sleep in the same bedroom with you?
|
For this question, the "no" percentage seems high. Perhaps some people misread the word "bedroom" as "bed." |
10. Masturbation Locations
Question: Where do you masturbate?
|
(a) always or almost always in the bedroom | 33.8% | |
(b) always or almost always in the bathroom at home | 7.4% | |
(c) usually in the bedroom, but sometimes in the bathroom | 33.5% | |
(d) usually in the bathroom, but sometimes in the bedroom | 15.5% | |
(e) usually somewhere other than the bedroom or bathroom at home | 9.8% |
Among those who share a bedroom, 24.1% chose response (a).
11. Public Masturbation
Question: How often do you masturbate in a public bathroom or other public place?
|
(a) rarely or never | 70.9% | |
(b) sometimes (5 to 50% of the time) | 28.6% | |
(c) most of the time | 0.5% |
12. Privacy
Question: How often are you able to take as much time as you want to masturbate?
|
(a) rarely or never | 3.4% | |
(b) sometimes (5 to 50% of the time) | 38.7% | |
(c) most of the time | 57.9% |
Among those who share a bedroom:
|
(a) rarely or never | 6.0% | |
(b) sometimes | 48.1% | |
(c) most of the time | 45.8% |
13. Session Duration — Leisurely
Question: When you're able to take your time, about how long (on average) does it take you, from beginning to orgasm?
|
(a) less than 5 minutes | 9.9% | |
(b) 5 to 10 minutes | 36.6% | |
(c) 10 to 20 minutes | 32.8% | |
(d) longer than 20 minutes | 20.8% |
This works out to a rough average of 14.0 minutes per leisurely masturbation session.*
Breaking out this average by age group:
|
• ages 11-15 | 11.7 minutes
(9.6 minutes for ages 11-13 only) | |
• ages 16-21 | 14.3 minutes | |
• ages 22 and over | 16.4 minutes |
*Calculated using the same method as in question #5, with 3 minutes for response (a) and 30 minutes for (d).
14. Session Duration — Hurried
Question: When you want to orgasm quickly, about how long (on average) does it take you, from beginning to orgasm?
|
(a) less than 1 minute | 9.8% | |
(b) 1 to 2 minutes | 44.7% | |
(c) 3 to 5 minutes | 36.4% | |
(d) 5 to 10 minutes | 8.3% | |
(e) longer than 10 minutes | 0.9% |
This works out to a rough average of 2.9 minutes per hurried masturbation session.*
Breaking out this average by age group:
|
• ages 11-15 | 2.7 minutes
(similar for ages 11-13 only) | |
• ages 16-21 | 2.9 minutes | |
• ages 22 and over | 3.1 minutes |
|
The ability to deliver a quick orgasm doesn't wane as much with age as you might think. However, as we get older, we learn to take more time with our leisurely sessions. |
*Calculated using the same method as in question #5, with 30 seconds for response (a) and 15 minutes for (e).
15. Age of First Orgasm
Question: At what age did you begin to masturbate to the point of orgasm?
|
(a) 11 or younger | 26.6% | |
(b) 12 | 34.8% | |
(c) 13 | 22.2% | |
(d) 14 | 10.4% | |
(e) 15 | 3.9% | |
(f) 16 or older | 2.2% |
This works out to a rough average of 12.1 years. People who started masturbating at age 12 or younger (average present age: 20.3) currently masturbate an average 8.7 times per week; those who started at age 13 or older (average present age: 21.7) currently masturbate an average 6.7 times per week.*
|
Readers who masturbate often are more likely to have begun masturbating at an early age. It's also possible that early masturbation tends to result in more frequent masturbation later on. |
*Calculated using the same method as in question #5, with 10 for response (a) and 18 for (f).
16. Age of First Ejaculation
Question: At what age did you begin to ejaculate semen? (Skip if you don't yet ejaculate semen.)
|
(a) 11 or younger | 8.6% | |
(b) 12 | 34.1% | |
(c) 13 | 35.0% | |
(d) 14 | 14.8% | |
(e) 15 | 5.0% | |
(f) 16 or older | 1.6% | |
no answer | 0.9% |
This works out to a rough average of 12.8 years.*
|
This question did not distinguish between masturbation and nocturnal emissions. Someone who began masturbating after having nocturnal emissions could answer this question two ways, depending on how he interpreted it. |
*Calculated using the same method as in question #5, with 11 for response (a) and 16 for (f).
17. Ejaculation Force
Question: In one of your better ejaculations (while lying on your back), how far does the semen get ejected from your penis? (Skip if you don't yet ejaculate semen.)
|
(a) less than an inch/dribble | 4.9% (average age: 19.1) |
(b) 1 to 6 inches — around your
......belly button or lower chest | 26.7% (average age: 19.4) | |
(c) 5 to 15 inches — your upper chest | 36.6% (average age: 20.8) |
(d) more than 15 inches — past your
......chest | 31.0% (average age: 22.5) | |
no answer | 0.9% |
Percentage of readers responding (c) or (d), by age group:
|
11-14 | 52.6% | |
15-16 | 64.8% | |
17-21 | 72.0% | |
22-35 | 80.2% | |
36 and over | 72.0% |
Percentage of readers age 16 and over responding (c) or (d),
by penis length (see question #26):
|
Shorter than 6" | 66.7% | |
7" or longer | 81.8% |
|
Ejaculation force generally increases with age, peaking in early adult life; it seems to drop off slightly at middle age. Readers with longer penises tend to ejaculate their semen further than those with shorter penises. Why is this? There are two possibilities: First; it may be that certain readers exaggerated their penis size and also tended to exaggerate their ejaculation force. Or, it may be physiological: The wave-like nature of the muscular contractions of ejaculation actually causes a wave-like contraction of the corpus spongiosum all the way up the length of the penis. This might cause a kind of acceleration that would explain the findings of the Survey. (For more on the ejaculation mechanism, see JackinWorld Science Corner. |
18. Feelings After Ejaculation
Question: How do you usually feel after you ejaculate?
|
(a) happy/relaxed | 89.2% | |
(b) guilty/depressed/upset at myself | 9.5% | |
(c) nervous/uptight/angry at the world | 1.3% |
Among the very religious, the guilty percentage rises to 14.6%. Among the very religious who have been reading JackinWorld for less than 2 months (see question #20), this percentage rises further to 18.6%. Among non-religious readers overall, the percentage who feel guilty after ejaculating is 7.0%. Among non-religious people who have been reading JackinWorld for at least 6 months, the percentage falls further to 4.3%.
|
Religious readers are twice as likely to feel guilty after masturbating than non-religious readers. The longer someone reads JackinWorld, though, the less likely he is to feel guilty after masturbating. |
19. JackinWorld Influence
Question: What is the biggest effect JackinWorld has had on you?
(a) now I feel much better about
......masturbating | 19.0% | |
(b) I've learned new techniques | 21.8% |
(c) I've been able to see how other
......people experience masturbation | 47.7% | |
(d) it hasn't had much effect at all | 11.5% |
Among the very religious, the percentage that chose (a) is 18.7%; among the non-religious, the percentage is 16.1%.
|
Religious readers don't consider guilt-reduction JackinWorld's greatest value much more than non-religious readers do — even if the site does reduce their guilt somewhat over time (as question #18 would indicate). |
20. JackinWorld Reader Tenure
Question: How long have you been reading JackinWorld?
|
(a) since late '96 — I'm a lifer! | 17.0% |
(b) I found it in winter or spring of
......this year | 23.3% | |
(c) I found it last summer | 24.7% |
(d) I just found it within the last one
......or two months | 35.0% |
21. Handedness
Question: Are you right- or left-handed?
|
(a) right | 85.8% | |
(b) left | 13.4% | |
no answer | 0.8% |
22. Hands Used in Masturbation
Question: Which hand or hands are you usually using when you ejaculate?
|
(a) right | 68.5% | |
(b) left | 16.2% | |
(c) both | 15.4% |
Among right-handed readers:
|
(a) right | 74.4% | |
(b) left | 10.3% | |
(c) both | 15.3% |
|
Unfortunately, this question was poorly phrased; the word "using" wasn't clearly defined. It should have read, "Which hand are you usually using to stimulate your peniswhen you ejaculate?" There also should have been an option for no hands, since some people masturbate without using the hands by rubbing their penis on something. We'll have to re-ask this question in the next Survey. |
23. Free-Hand Use
Question: If you have a free hand, what is it usually doing when you ejaculate?
|
(a) not much | 36.2% | |
(b) massaging my scrotum or crotch | 40.3% | |
(c) stimulating my anus | 8.8% |
(d) massaging my chest, nipples,
......or elsewhere | 13.5% | |
no answer | 1.2% |
24. Penis Hang
Question: When you stand up, does your non-erect penis hang to the left or right at all?
|
(a) no — it hangs straight down | 56.7% | |
(b) it hangs to the left slightly | 27.2% | |
(c) it hangs the right slightly | 15.3% | |
no answer | 0.7% |
Among right-handed readers who masturbate with the right hand only:
|
(a) straight | 57.0% | |
(b) left | 27.2% | |
(c) right | 15.8% |
Among left-handed readers who masturbate with the left hand only:
|
(a) straight | 65.5% | |
(b) left | 25.0% | |
(c) right | 9.5% |
|
It's commonly believed that a penis hanging to one side is caused by the person masturbating with the other hand. From this Survey's findings, this appears to be a myth. It probably has to do with how the penis is usually positioned in one's pants; over the years, this may cause the penis to hang to that side. |
25. Penis Curve
Question: When you look at your erect penis from above, does it curve to the left or right at all?
|
(a) no — it's straight | 55.5% | |
(b) it curves to the left slightly | 29.1% | |
(c) it curves to the right slightly | 12.8% |
(d) it curves sharply to the left or right
......(more than 20 degrees or so) | 2.6% |
Among right-handed readers who masturbate with the right hand only:
|
(a) straight | 54.9% | |
(b) slight left curve | 30.4% | |
(c) slight right curve: | 11.9% | |
(d) sharp curve: | 2.9% |
Among left-handed readers who masturbate with the left hand only:
|
(a) straight | 62.7% | |
(b) slight left curve | 27.7% | |
(c) slight right curve | 8.4% | |
(d) sharp curve | 1.2% |
Among those who began masturbating to orgasm at age 11 or earlier:
|
(a) straight | 55.5% | |
(b) slight left curve | 28.5% | |
(c) slight right curve | 12.9% | |
(d) sharp curve | 3.1% |
|
It's been said that someone who begins to masturbate well before the penis is fully grown will be more likely to have a penis that curves to one side. From this Survey's findings, though, this doesn't seem to be the case. However, for some reason, a penis that curves to the left is much more common than one that curves to the right — even among left-handed people. And for some reason, left-handed people report significantly straighter penises overall than right-handed people. This is very mysterious. |
26. & 27. Penis Size
Readers were asked to measure their erect penis for length and circumference using uniform, precise methods. They were told: "If you have even the slightest temptation to lie or exaggerate your measurements on this survey, or if you aren't interested in getting a precise measurement by using the methods outlined below, please do us all a favor and skip the next two questions."
Length
This was the measuring method given for length:
With a rigid ruler handy, get a full erection. Lay the ruler along the top of your penis, and press the end of the ruler firmly against your body (where the pubic hair is). Hold your penis against the ruler with your hand, straighten out as much as possible any curvature that may exist, and try to hold your penis so that it's sticking straight out from your body. Then determine the ruler reading at the very end of your penis.
Question: The non-exaggerated length of your erect penis, as measured by the above method (please don't fill in if you didn't follow the directions):
Overall average: 6.07"
By age:
|
• age 12 | 4.47" | |
• age 13 | 5.28" | |
• age 14 | 5.67" | |
• age 15 | 5.95" | |
• age 16 | 6.14" | |
• age 17 | 6.20" | |
• age 18 | 6.13" | |
• ages 19 and older | 6.30" |
|
By ethnicity (age 15 and over only):
|
• Blacks | 6.89" | |
• Asians | 5.33" | |
• Whites | 6.22" | |
• Hispanics | 6.15" | |
• Native Americans | 5.66" |
|
Among those who began masturbating to orgasm at age 11 or earlier: 6.08".
Among those who began masturbating to orgasm at age 14 or later: 6.03".
Readers age 16 and over whose penis is shorter than 6" masturbate an average of 6.8 times per week; those with a penis 7" or longer masturbate an average of 8.0 times per week.
|
In the average male, the penis reaches close to its adult length by about age 14 but continues to grow slowly until about age 16. Again, the sample size of some minority groups was too small for definitive statistical analysis, but according to these findings, people of African heritage report the longest penises on the whole, followed by whites, Hispanics, and Native Americans. As a group, Asians reported the smallest penis sizes among the ethnicities. Penis size and masturbation at an early age are probably unrelated. However, readers with larger penises currently masturbate slightly more frequently than those with smaller penises. Why? Who knows? |
Circumference
This was the measuring method given for circumference:
With a flexible tape measure or piece of string handy, get a full erection. Measure the distance around (NOT across) the fattest part of your penis. In other words, wrap the tape measure or string around the shaft and measure it that way.
Question: The non-exaggerated circumference (not diameter) of your erect penis, as measured by the above method (please don't fill in if you didn't follow the directions):
Overall average: 4.37"
By age:
|
• age 12 | 2.98" | |
• age 13 | 3.88" | |
• age 14 | 3.99" | |
• age 15 | 4.19" | |
• age 16 | 4.33" | |
• age 17 | 4.31" | |
• age 18 | 4.60" | |
• age 19 and over | 4.63" |
|
By ethnicity (age 15 and over only):
|
• Blacks | 4.55" | |
• Asians | 4.20" | |
• Whites | 4.48" | |
• Hispanics | 4.42" | |
• Native Americans | 3.74" |
|
Among those who began masturbating to orgasm at age 11 or earlier: 4.43"
Among those who began masturbating to orgasm at age 14 or later: 4.35"
|
On the average, the penis seems to grow in circumference slightly longer than it grows in length, reaching a maximum in the late teens. Findings in relation to ethnicity and age of first masturbation were similar to the findings for length. |
28. Hypothetical Question #1
Question: If you were with a group of three or four male peers and the topic of masturbation came up (without anyone saying they did it), and someone asked you point-blank if you masturbated, what would you say?
|
(a) I'd say I masturbate | 70.3% | |
(b) I'd say I don't masturbate | 9.4% |
(c) I wouldn't answer, would ask
......someone else, or would change
......the subject | 19.6% | |
no answer | 0.7% |
Percentage that answered yes, by age group:
|
• 11-14 | 53.0% | |
• 15-16 | 64.7% | |
• 17-21 | 74.2% | |
• 22-35 | 82.5% | |
• 36 and over | 90.8% |
Of those who usually feel guilty after masturbating:
|
(a) yes | 48.7% | |
(b) no | 23.9% | |
(c) change subject | 27.4% |
|
Not surprisingly, younger people are less likely to admit they masturbate than older people. In the 36-and-over group, only two respondents — both in their 70s — would deny that they masturbate. Also, people who feel guilty about masturbating are much more likely to deny that they do it. |
29. Hypothetical Question #2
Question: Would you ask a male friend to masturbate with you if you knew for a fact he'd say yes and wouldn't tell anyone about it?
Among the very religious:
|
Surprisingly, religion has little or no impact on how a reader would handle this situation. |
30. Hypothetical Question #3
Question: If a male friend asked you to masturbate with him and you knew for a fact nobody would find out about it, would you do it?
Among the very religious:
|
Again, religion has little or no impact on how a reader would handle this situation. |
|
