Your post made me smile Chiannaa. We have the opposite thing going on, and I would love to get my wife to talk dirty to me.
I have one partner that's fairly stoic, and I can usually get him to give me some dirty talk if I lead. So, things like... "How does my pussy feel right now?" "Tell me how much you want to cum..." "Do you like squeezing my tits like that? Tell me..." "What if I did [whatever] to you right now? What would you do next?" "Are you my filthy slut? Tell me how dirty you are..." Sometimes it works, and sometimes I get one-word answers. Honestly, some people just don't have the imagination for it. Other people (me included, sometimes) find that having to verbalize pulls their attention away from the sensations and actually decreases whatever is going on in their body.
Yea, but im one that gets off on verbal talk. Sometimes i just tell him to talk about anything while im trying to get there. Lol it works for me!
