I'm was wondering if someone could help me cause i've been cumming alot less and idk wats wrong cause i usually cum all the way up to my chest now it barely even touchs my stomach...
You don't say how old you are or how long ago it was hitting your chest. Fifty years ago I had to put something over it if I was on my back masturbating or it would hit me in the face, but not now.
However, that's hardly the point. All it needs to do is dribble out. The distance between the tip of your penis and the entrance to her cervix is easily swimmable by those little swimmers. When you're in there you're not injecting them into the egg, you're just dropping them off in the waiting room.
