I'm sure we've all heard the anecdote that man isn't supposed to lay with another man because God created Adam and Eve, not Adam and Steve. I, personally have wondered why this anecdotal evidence doesn't lend itself to other theories of human sexuality. Particularly the widespread sexist/misogynistic belief that men have higher libidos and are by nature "hard wired" to cheat, spread their seed, be polygamous, etc.
If men aren't supposed to be gay because God created Adam and Eve and not Adam and Steve, then i'd like to add that men aren't supposed to behave like feral beasts roaming the bush because God created Adam and Eve and not Adam and Eve and Tiffany and Stacy, and Cassandra, and Melissa.
Just a thought!
