I can't seem to come up with an answer – got any ideas?
That's a good question! I assume you're talking not about the sound of a lubed-up hand on the penis, but rather the "squishy" sound that sometimes happens even without lube. I think I have the answer. Just inside your penis head, the urethra (the tube that carries urine and semen) widens out a bit, forming a little "reservoir." When you masturbate, that "squishy" sound is air going in and out of the urethra to and from this reservoir. If you secrete a lot of Cowper's gland fluid ("pre-cum"), you may have noticed that it tends to get a little bubbly when you masturbate – that, too, is a result of air entering and exiting in this way.
What do you think about when you masturbate or have sex? Would you tell your significant other if they asked?
