dude if we're basing what god wants based on how bodies are designed, then clearly he wants everyone to be gay
most dudes have prostates. accessible via ass. Most dudes also have dick sucking lips that make good suction. (The feminine beauty ideal of "pouty" lips just means less skin between the nose and mouth, and the more skin you have there, the better seal you can make.) it's like the male body is generally designed for gay sex.
not to even mention that like, you know what people with bodies similar to yours would like. girls know how to please girls, to the point that it's a meme even among a lot of straights. Etc.
basically, if you're gonna be bioessentialist like a loser, know that i can come up with reasons why things should actually be bioessentialist in the other direction. Because It's Almost As If The Metric You're Using Is Arbitrary And Can Be Made To Support Anything If You Think About It For Five Seconds :D
