Condom use question: After the male ejaculates in a condom, is it ok to remove that condom carefully and put a new one on and continue having sex?
Yes — replacing the condom after ejaculation if you continue to have sex is exactly the right thing to do. Using a new condom prevents semen from leaking out of the condom and into the vagina. In order to remove the condom correctly, he should hold onto the base of the condom as he pulls out, to make sure that no semen leaks out.
