We have been together for a while now. But every time he calls me and asks If I will talk dirty to him. I freeze up and don't know what to say. Or sometimes I just repeat the same things, so it get's boring, and less exciting. I have things in mind, it's just the heat of the moment I get really nervous! Guys, what should I say? How should I say it? How do I make it last? And what types of things do you like?
