Ejaculation (aka “cumming”) is when semen spurts out of the opening of the urethra in your penis, usually during sex or masturbation. Premature ejaculation is when you ejaculate (cum) before you want to — usually before your partner has an orgasm.
If premature ejaculation happens more than half of the time you try to have sex, you are not able to delay ejaculation, or you or your partner feel bothered, annoyed, or frustrated with it, there are several treatments available to try.
