The desire I'm referring to is the exhibitionist raw fuck roid load gang bang muscle pig thing. Straight/gay exist in actualities, so if he was in a straight relationship and only had sex with women up until recently, he was, for all intents and purposes, straight. Considering he got into this via admiration on twitter, he might not even be attracted to men, just attracted to the attention men give him, because let's be real women are not into the muscle worship shit. And when that desire was fulfilled he went back to what came natural to him.
