F52.4: Premature ejaculation

Sex involves different phases that lead to mental and physical changes. First of all there is excitement, at which point the person wants sex. Then, for example, one’s blood pressure rises and breathing gets faster. The external genital organs also swell up in both the man and the woman. When the excitement reaches a certain point, there is an orgasm. After the sexual high, one feels satisfied and the body relaxes. The blood pressure falls, for example, breathing returns to normal, and one may feel tired.

With sex, after a certain amount of time one normally has an orgasm. In the case of the man, an orgasm involves ejaculation. In your case, for example, the ejaculation is happening early so that it is unsatisfactory for the sexual partnership. The ejaculation may also occur, for example, before penetrating the vagina.
