From an objective point of view, the preference for anal sex is not a psychological disorder, but probably just a category of people’s preference. However, from a medical professional point of view, there are great hazards and risks associated with anal sex. First of all, the anus is not as flexible as the vagina and can be easily fractured. Secondly, once the anus is torn during anal sex, the chance of contracting germs increases dramatically and the consequences can be very dangerous. The vagina, on the other hand, is the safest place to have intercourse because it has a natural barrier that protects it from bacterial infections.
