Sexual intercourse

Briefly and succinctly explained, this is the sex. The abbreviation for sexual intercourse is SI. The German abbreviation for sexual intercourse is GV (Geschlechtsverkehr). In the actual sense, the word sexual intercourse or coitus meant the actual sexual act between a man and a woman, i.e., the time when the man inserts his penis into the woman's vagina. With increasing sexual acceptance and also tolerance, the word sexual intercourse came to be used not only for the classic heterosexual act, but also for the sexual act among homosexual couples. Many use this term for everything that has to do with sexual stimulation. Thus, the classic “tit-fuck”, cunnilingus and anilingus are also considered sexual intercourse. The aim of this act is to bring one, or at best both partners to climax, i.e., to orgasm. Unlike most animal species, humans have sex for fun. Sexual intercourse releases endorphins in the brain, and we feel pleasure, feel aroused and are rewarded with an orgasm. However, the real purpose of sexual intercourse is much more mundane than the satisfaction of desires, namely that of procreation.

When the man ejaculates in the woman's vagina during sexual intercourse, sperm from his testicles penetrate the woman's uterus. There, the sperm fertilize the egg, provided the woman is ovulating or about to ovulate. The sperm cell and the egg cell divide and develop over the course of 9 months into a new living being, a baby. Sperm can survive up to five days under ideal conditions in the woman's uterus. On average, German women and men have sex five times a week up to the age of 35. From then on, sexual intercourse decreases. After all, 55-year-olds still have sex four times a week. Of course, we are talking about average figures here, but they also correspond to studies from different countries. According to an Australian study, people have sex for an average of just under 5 minutes each time they have intercourse. There was a lot in the study between 33 seconds and 44 minutes. BUT: This is only about the actual act itself, that is, measured from the moment the penis enters the vagina to the completion of the act through, usually male, climax. This does not include foreplay, cuddling or even a second round.
