Ejaculation is the release of semen from the body. Premature ejaculation (PE) is when ejaculation happens sooner than a man or his partner would like during sex. PE is also known as rapid ejaculation, premature climax or early ejaculation. PE might not be a cause for worry. It can be frustrating if it makes sex less enjoyable and impacts relationships.
