Virtually none. Straight men don't live in social conditions that permit them to be deluded about their own attractiveness. An obese woman will always be able to find some desperate scumbag to throw a fuck in her; good luck getting the same as a man with no sexual market value. I should clarify: I don't imagine a gay man of the old school would have much luck either. Gay men used to take pride in their appearance. From the outside looking in my impression is that the worst thing they ever did was ally themselves with gender studies crybulles, who are now starting to turn on them for being a 'privileged class' of fags.
