Sex is not a wizard, whatever magical-seeming properties it might possess in its better forms. If your friend says to you, "You're being mean, you need to get laid," your problem is not sex. Your problems are that you might be acting like an asshole, and your friends are definitely idiots.
Thou shalt not lie with mankind, as with womankind: it is abomination.' (Leviticus 18:22). That means simply that it is foul to do to other men what men habitually, proudly, manfully do to women: use them as inanimate, empty, concave things; fuck them into submission; subordinate them through sex.
