Hell, even speaking as a gay man Henry Cavill's not even my type but I'd still let him plow me like a snowy road if he seemed even a little interested.
Henry Cavill isn't gay but I did some sleuthing back in the day and it brought about some very interesting results. This was pre-Superman, maybe even pre-Tudors era tea but I discovered it around that time. I somehow found out about a friend of his on Facebook, this guy would somewhat regularly feature Henry in his photos. People didn't really know who he was then but Henry was (and obviously still is) so striking this guy would put in the captions "He's STRAIGHT so don't get any ideas" because his friends would drop their panties in the comments. This friend of Henry's was obviously gay so I looked him up and he saw had a blog with poetry and photography. Lo and behold, one of the posts was a fresh-faced Henry Cavill beside some poem which leads me to believe he was enamored (wouldn't you be?).
Anyways, it turns out this guy also knew (maybe dated?) Dan Renzi, a contestant from Real World/Road Rules shit who happened to be a columnist/blogger. He had some column in a gay publication I forget where he'd basically report on his own friends' antics a la Carrie Bradshaw. Anyways, I wish, wish, wish I could remember where these columns were published so I could find it again but in one of them he detailed a friend of his who was roommates with an extremely hot British actor. I deduced pretty quickly it was Cavill and this guy I discovered. There were maybe two posts fleetingly mentioning Cavill though not by his name.
BUT what he did say was that this hot, fit young British actor did walk around naked in the apartment in plain view and that his friend saw his "BBC" or "big, British cock" and didn't really mind being seen. So maybe Cavill's not gay but he likes attention...that's something.
