After you've ejaculated once into the condom during sex, are you supposed to like, put on another because it might, I don't know, overfill? Because I and probably a lot more others can orgasm more than once and I was just wondering what to do with the condom after you've done it the first time and still want to continue.
Condoms and ejaculating more than once
To properly prevent pregnancy, you need to take the condom off after you ejaculate once, and put a new one on. It is not safe to use the same condom again, once you have already ejaculated in it.
It's not so much that it will overfill, it's that the semen can get squished out through the sides.
