I get a lot of emails from women asking all sorts of questions. I've heard it all.
One question I get quite often, is from women who are afraid to sound stupid, so I want to talk about this.
Unlike the episode of SATC where Miranda says something to her boyfriend while in the bedroom and he gets up and leaves....that doesn't happen.
Chances are, if you're secure enough to try talking dirty to your guy, then I highly doubt that anything you say will completely turn him off. If anything, he'll probably laugh.
If you've done any research for dirty talk online, everyone says 'start slow', and it's actually decent advice. In the beginning, you should just ask general sexy questions to see what he likes: "What do you want me to do?" "Does it feel good when I do this?" "Do you like when I do this?". That way you can play it safe, then once you're comfortable with getting reactions, start adding in some playful names: "how does that feel tiger?"....etc..etc..
If you're worried about sounding stupid, don't be. If your guy is lucky enough to have YOU want to learn to be good at dirty talk, he should know not to mess it up.
Go do it and have fun. It's worth it.
