Interesting. I had come to that conclusion too. Unless, of course, they start out "straight" and morph or were maybe in the military during DADT. Or they have them for cover. But for the most part, there sure seems to be a similarity in tattoos on gay men in porn and a similarity in the tattoos of straight men that I know who are definately straight young men. Someone could probably manage to get a doctoral thesis out of some of this stuff, huh?
