Now I have been having sex since I was 15. I have seen sex ed movies and how the ejaculation process works. My question is this: When you are working up to ejaculation is semen building up in a type of reservoir? It would seem so since when you get to the point of no return the semen comes from somewhere and it seems to me that it would all have to stage somewhere first before heading out the door (so to speak). If you get close to the point of no return and stop and let everything subside and just go on with other business where does that semen buildup all go? What say you?
