It's not abnormal or weird, some men just get really into the moment. And he might even think it turns you on. If you don't like what he's saying and it really bothers you, then try to express to him that his dirty talk does not help you feel sexual, and it makes you uncomfortable. Tell him if it makes you feel degraded and you would rather that he keep silent. If he has to talk then let him know he needs to be more affectionate & tasteful in what he says. And if he can't handle that, then you should really consider finding a new boyfriend. Sex is supposed to be a mutually pleasing experience. On the other hand, i can tell you that most guys are very quiet, and talking and moaning can really be a turn on...it just has to be done in a respectful way. Try to get into it if you can, i know it may seem awkward and strange at first but you might find that you like it. Sex gets better when you are open to trying new things... so experiment with it. : ) Adult toys can be fun too. Be open minded, it can help your sexual relationships from becoming boring or routine-like.
