lol I'm totaly straight bro. It's just you notice some fighters have massive legs and ass (I think Tyson Griffin was a good example of that).
It's no different than male fans admiring male fighters bodies and saying shit like "oh this fighter is ripped", or "damn when Machida dropped in weight to MW he has 8 pack abs and looks like he's in mega shape".
Looking at fighters bodies is something everyone engages in whether they realize it or not. It's not a matter of being gay, it's more like "holy shit, what do I have to do to look like that fighter".
Maybe benson does leg day every day lol
