Why do straights turn into gays when separated from women for extended periods of time??

They don’t “turn into gays” in those situations. It’s simply a case of Men having intense and constant sexual needs, and those needs require satisfaction in one way or another. When you have a group of Men constantly together in a place without females (like prison) – and they all have similar raging sex drives – sexual acts are going to happen. That doesn’t mean they’re now gay. They are simply making do with whatever circumstances they have in the moment.
