I have always felt that eating pussy is nasty, that's why I do it. I love the smell and taste of a woman and her secretions. Guys are nasty, so are girls. Most girls swallow our cum. Some of us will go down on our ladies even after we cum in them. They like it because it's nasty, we do too! If you're reasonably clean before you start he'll love eating you. If he doesn't there's something wrong with him not you.
