In all fairness, Dan Savage, who writes the syndicated weekly sex-advice column "Savage Love," is militantly gay and fields inquiries from every possible permutation of attractions and antipathies that God's green earth affords. He receives queries (so to speak) from male, female, and undecided gays, straights and bents of all directions. When, after consulting knowledgeable informants, he addresses both straight and gay readers' questions about techniques for managing female plumbing, he often adds that he is personally revolted by the mental images that accompany contemplating any of it. It's funny. His point is that you can't help liking and disliking what you like and dislike; all you're obligated to do is leave people alone who doing that in their own way, unless they're actively suppressing your liberties.
I don't share many of his views, but it's refreshing to hear the outspoken distaste that a gay man expresses for phenomena that the majority unconsciously assume is universally attractive. Shoe on the other foot; instructive for our empathy.
