Some parts of this post might be explicit so be warned. I tried to do some research on this but I couldn't find all the answers. When one doesn't ejaculate, I can imagine the balls filling up with semen but when it is all filled up, what happens? I know that producing semen required a lot of effort of the body. If it stops producing sperm, what will happen? Ejaculating too much definitely strains the body and one might even have shortage of zinc or other vitamins and minerals but not ejaculating at all, is that not equally bad?
