Why is the male g-spot up their ass

This question is specifically directed to religious individuals (people who are apart of religions who see homosexuality as a major sin). I truly don’t understand why God would put the male g-spot in the rectum (the prostate) while also promoting how disgusting homosexuality is, I’d also like to add that in certain religions your also not allowed to do things like pegging or just sticking things in your rectum in general (I’m aware gay people aren’t the only ones doing that). I just find it a little odd why God would make the place men feel most pleasure supposedly “sinful”.
