If Guy on Guy is gay...then so must be girl on girl. ,and if that's the case then every girl doing porn must be a lesbian because they ALL do girl on girl.! For your information, a lot of straight guys enjoy stimulation of the prostate gland,whether it be by a strapon, butt plug, etc. It is similar to a woman's "G" spot.... so your argument is lame .Gee ,wouuldn't that make all who watch Gay by association?? Just a thought ..............
