Attractiveness has NEVER been a barrier determining if a woman will or won’t perform anilingus. It’s a very intimate thing to perform and the deciding factor comes down to trust. Trust that she won’t be pushed into doing it at anything other than her pace, trust that she will decide what and how far she goes in doing it. Most men are woefully unaware that many women really want to do this and have it done to them, but insecurities and fear of criticism are the holdbacks in expressing interest in doing this. I’ve managed to coax even the most reluctant women into doing anilingus over the years, it’s a sexual act that most people secretly want to do and have done to them.
