So I have two problems. Me and my boyfriend enjoy having sex, I had never suck dick before and I know he wants me to do it to him and every time we about to have sex I am thinking about doing it but I always think I'm going to do it the wrong way or he is not going to like it, so can I get any advice? Also when it comes to riding it m, I am so inexperienced any advice ?
