Some people derive sexual pleasure from their anus. This is bizarre and unhealthy. I am not suggesting that it is unethical or that people should be ashamed of this.
We have sexual urges for reproductive reasons. Our instincts usually have a biological purpose. Rectal sex has no procreative purpose. Indeed it is wasteful. It can cause people to catch infections because of the bacteria in the rectum. Men can contract such infection and women can catch vaginal infection if their boyfriend is double dipping. Bum sex caused lower bowel damage. This is before we talk about communicable diseases. At the very least botty sex is a waste of energy and semen. I am not suggesting people should refrain from it. If they find it enjoyable then go ahead.
Some people like to stimulate their anuses for the sake of sexual arousal. Some men like prostate massage including straight men. But putting one’s hand inside one;s rectum is unhealthy. Everyone knows that this is the filthiest part of the body.
Gay men often like rectal intercourse. Being a homosexual is not shameful or immoral. My point is that biologically it does not make sense. Let these men do as they wish. There may well be a gay gene. I suspect it is a misfiring or the reproductive urge. We now have IVF. But if we did not have IVF we would need people to be straight – most of them. If too many people were gay the human race would have become extinct.
I suspect those who have a penchant for anal sex have a gene that has gone wrong. The generative instinct has been a little misplaced. They are doing something a tad unhealthy and unproductive. Let people enjoy their sexuality however they want. This is a comment and I am not being judgmental.
