Mom, I've got friends with benefits, but at least I'm not gay.
I think it takes more than lifestyle posturing for a man to put his lips around another man’s penis or that that penis into his anus.
I think it is safe to say that it takes some pretty serious mental illness to do those things. In fact, it can be argued that a guy putting on a dress and hobnobbing with a herd of fat chicks at the mall is likely not as mentally sick as everyday homo behavior.
It’s the Overton Window effect. The range of acceptable behavior is shifted over years to a new paradigm, almost without us noticing.
