For example, America has become more sexually enlightened. In the 1950s, the average length of time was three minutes. In the 1970s, the average time was seven minutes, and in the 1990s, the average length of time was nine minutes. There is an Irish culture where the average length of time is 90 seconds, and in India, they withhold orgasm up to one hour. In America, there is a big problem with premature ejaculation that is very treatable.
Premature ejaculation has no known cause.
Men might masturbate before sex to go longer during sex. Sometimes it works and sometimes it doesn't. Sometimes men try to think about distracting things like balancing their checkbooks, but that doesn't work either. There are some techniques that a sex therapist can teach you that will treat it in a few weeks. Sometimes the male's partner will try to bring them to orgasm by manual stimulation.
