so, i must say, i am a straight male, but i love nothing more than seeing men go at it, especially with women watching. and the thought of a huge, hard, penis in the mouth of another man, or in other places sends me over the edge. who cares to share?
Probably a good many straight males find it exciting to see another penis if it's erect and impressive. But most of us are restrained by the expections of other and of ourselves.
