I'm not really into anything "XXX", but I am not hesitant to say I really appreciate a good looking male physique.
I believe there're a lot more STR8 guys who are erotically turned on by the same, but won't ever admit it.
In fact, psychological tests reaffirm the fact that most guys are "average" on the "Bell Curve" of sexual orientation and attracted to both girls and guys. I remember an old saying that "There's a little bit of Gay in everyone".
