You might be interested in this-- it's by a male feminist who's working on how to have feminism which is genuinely friendly to heterosexual men.

Another young guy, one of my best students, told me that he felt as if he’d been set up for failure, as if Jensen and I were positing abstinence from pornography as the sine qua non of being a decent male. “If I masturbate to porn can I still be a good man” was the question I got from more than one anguished participant in the class. And if several of the students were willing to divulge such private pain to me, I can only assume that still others felt the same way but kept silent.

I suspect the problem goes deeper than the specifics of feminism, though those are worth addressing. A lot of people interpret moral advice in self-damaging ways, and I'm not sure what's going on there. It seems like a taught vulnerability.
