I'm wondering if maybe he's getting hit on by gay men and he isn't gay. Hard to imagine a guy would be put off by female admiration.
The correct answer is that he is hetero but feels guilty for not being gay, so he's trying to be gayer, but it isn't working because more females than males are attracted to, and are attractive, to him. The conflict and cognitive dissonance has made him go crazy, ergo this odd OP.
