It can be a turnon. I certainly don't find it offensive. I've watched some videos that show bi activity and the guys are getting it on as much as the girls.
I've always thought same sex activity made alot of sense. Who can satisfy a man better than another man? Just like a woman can satisfy another woman better. Usually. There are always some things the opposite sex can do better. But someone of the same sex knows exactly how it feels when something is done to another. Seems logical.
