I believe a good number of men are bisexual since a lot of men enjoy watching other men have sex on camera and are aroused by it. Men buying sports magazines with images of men sexualized.
Watching a body building competition is much different than a man on camera butt naked, fully aroused and moaning. A lot of gay men will watch straight porn if the man has a nice body and stroke. Adding a woman definitely doesn't take focus off the man.
good thread... As a 60+ man -- to me there is nothing hotter than a smooth man OR woman, period. I'll take 'em both. Am I bi? for sure!I wonder if the older males have spent 30+ years wondering about having some kind kind of intimate contact with another man and during their older years realise that social stigma is not as important as when they were young. Maybe some older males just think that they should do what makes them happy.
