What a nonsense. How could a long term a primary function of every living being in this world - a procreation - set heterosexuals into "extreme" variant? Gays cannot reproduce. From a biological variant it is not normal behavior.The vast majority are actually a shade of bisexual such as yourself. Homosexuals are simply an extreme variant much like heterosexuality is at the other end.
If the nature or God made gays for each other, then anus could be prepared for a long term penetration. But it is not, a gay bowel syndrome, leakages etc. are common after time when it comes to anal sex - for gays and for straight.
You are guessing wrong, but I am not responsible for this. I just said that every minority thinks that what they do is perfectly normal. Whether they are gays, cannibals or people with serious mental illness in a mental institution.I am guessing you are trolling me at this point to compare homosexuals with murders, paedophiles, a sickness, a defect or a cripple. So I'm not going to waste any more time. Good luck.
