IIN to ask him to talk dirty?

That's a good question... How would I do this? Umm...ok I guess I would start with a quick conversion. Keep it brief. Men tend not hear anything past a couple minutes. I'm not even being sarcastic men are not born communicators like women are. I would just say this is something I really enjoy and I would like to explore it more,is there anything you want to explore? Ask him to think about it for a bit, don't put him on the spot. When he comes back with something, most importantly, don't laugh, but do it. Try to make him comfortable. I think just getting him outside of his comfort zone will make him more susceptible to want to try the dirty talk again. Show him that there's nothing wrong with experimenting a little. That it's healthy in the right environment. You just have to show him how good it can be.

And everybody has had different experiences with sex. I would venture to say that his haven't been as open as yours. Nothing wrong with that. Don't be worried. If you care about him just be patient and try not to get frustrated with him.

It took me many years to fully embrace my sexuality and I think everybody moves at their own pace. Don't give up. He'll come around. Come. Hehe.
