heres the thing, the more frequent you masturbate, the less will come out in each session. i guarantee you if you wait for a week without masturbating, you will be cumming like a porn star.

so no need to compare yourself to what you see in videos, because supposedly they 'store' up as well. as for having babies, you'll be fine. the amount of sperm your body produces in a day is insanely high, and as bigbear said, all you need is one.
