I got into anal sex at one time in my life, not because I was hot for it, but because my partner was curious and found she liked it. A lot of things turn me on, but all of them are enhanced by a partner who's aroused, willing, eager and curious. So it just seemed to be a natural place to go.
After a time, she decided that it didn't do it for her as much, and I was okay with that. As for finding it gross... when you're naked and sweaty and everything's clicking, many things become appealing that cast a different light in the cold reflection of reason and logic.
