I found this medical article quite interesting, it's always fascinating to find out how your body works The Straight Dope: How does ejaculation work?
Very interesting and readable article. I was amused by the suggestion that ejaculation may be a cure for nasal congestion. Thanks for sharing.
Interesting. The "pressure chamber" or point of no return is definitely different in every male, I would think. That is why some guys can last different times.
Wow! Very interesting. It doesn't seem like one particular thing is responsible for it. I mean there are people that can ejaculate hands free and sometimes even with a flaccid penis. I don't know how or why. Thanks for sharing!
