Religion and homosexuality

We all know that most major religions in the world dictate that homosexuality is wrong. Why is that? Here is my theory.
Religious rules are often designed to address some societal problem. I believe that the problem being addressed was men having too much sex with men. The reasons for heterosexual sex are obvious - it is needed for procreation. The reasons for homosexual sex are equally obvious - it is intensely pleasurable. I have no doubt that men were sucking and fucking each other long before religion became a dominant force in growing societies. And when societies started to organize around work and productivity, men having sex with each other all day became a problem.
I believe that if you took religion out of societies, homosexuality would be very widely practiced. Once AI takes all the jobs, maybe men will be freed up for homosexual sex once again!
