This method is fantastic and will give you an unbelievable sensation. You need a soft-bristle toothbrush. Use the brush to gently and slowly rub your balls and underside of your penis. It will give you a feeling like you've never had. You can fondle yourself for hours this way. When you take a break and start up again, you'll experience the same intense pleasure without ejaculating. You can use the handle of the brush to rub your scrotum with as well as the crack of your hole...it feels soooo good.
First, place a condom on your penis. Next, cut the top off a banana and scoop out the fruit, leaving a hollow peel. Get a plastic sandwich baggie and place the banana peel inside. Then put the baggie containing the peel in between the mattresses of your bed. If the mattresses are too firm, put a crumpled-up T-shirt on top and bottom of the baggie when it is between the mattresses. Finally, place your penis (with condom on) into the banana peel and start going. The condom reduces chaffing and also helps with the cleanup process.
I just wanted to throw a "5-hand" suggestion your way, as it is a shame this thing doesn't have the publicity it deserves. There is a children's toy out there called the Super Mondo Ball. You should be able to find it at most local toy stores or science-museum gift shops. It feels absolutely fantastic with the addition of your favorite lubricant. Benefits:
My masturbation technique requires a vibrating device. I use a men's Gillette M3 electric razor. Just remove the blades from the device and turn it on. Move the device around to find the "sweet spot" on the penis. Don't masturbate in any other way. A good position is to lie on your back. When the orgasm is about to occur, your penis will start to twitch, but you should continue to use the vibrating device rather than your hand. The semen may not squirt out (it may slowly drip out), but the orgasm is usually very pleasurable. It's like someone is torturing you with an orgasm.
