Until 1961 homosexual acts were illegal throughout America. The major surveys on homosexual behavior are summarized below. For example, bath houses and sex clubs in many cities have either reopened or were never closed. Semen contains many of the germs carried in the blood. Because of this, gays who practice oral sex verge on consuming raw human blood, with all its medical risks.
Rectal sex is dangerous.
Fisting was apparently so rare in Kinsey's time that he didn't think to talk about it. By 1977, well over a third of gays admitted to doing it. The rectum was not designed to accommodate the fist, and those who do so can find themselves consigned to diapers for life. Those who eat or wallow in it are probably at even greater risk. While the body has defenses against fecal germs, exposure to the fecal discharge of dozens of strangers each year is extremely unhealthy.
