Interesting point. Now let me ask yall, do you think being gay is a choice? Can someone be made gay or are they born gay? I know this might not totally translate, but I was in the pen with a dude, a cold blooded killer, who had been in a serious relationship with another con. Even killed a guy together in the max. But when I met him in the medium he was getting PFV's with a chick he was trying to marry. He used to joke and say "I'm not gay anymore". I know being inside is different circumstances, but still.....
the joint is the land of opportunists.
if we are talking about dudes going punk or getting turned out in the pen, it can be a multitude of different reasons.
non-alpha male, cowering down to his oppressor.
homo on the under on the streets, & seeks opportunity to get dicked down.
hustler that'll sell anything including his asshole
or someone who is not the
alone type seeking companionship in any which way he can.
IMO, there is situations where people can "Turn gay"
... chicks fed up with men fucking them over.
sexual deviants.
trendy EMO types
trisexuals (a muh fucker who will try anything)
But like
@BASEDVATO
said, more than likely something with the way the brain is wired or a chemical imbalance or suffa.
