How do I tell my boyfriend that I like him to talk dirty when we are at a fever pitch?

I don't believe that he'll think you're slutty. If you want him to start talking dirty at a fever pitch then you're going to have to get him used to the idea.

How about the next time he's getting down to business, ask him to tell you what he's doing or going to do to you. If he says "I'm entering your vagina with my penis" rather than "I'm going to stick this gigantic ______ into your f**king __________" then he's going to need more practise.

no way! Guys love talkin dirty. I always tell my woman I love her sweet pussy when I making love to her. She particularly likes it, when I whisper in her ear, all sorts of nasty tid-bits. Details freak people out, but yeah. Start by talking dirty to him. Tell him you love having his **** inside you.etc. he'll get the point.

try to talk while you guys having sex and been pleasure .

I would just start with something simple like "F" my pu**y. Right when you are at the "fever pitch" as you say. He'll go along with it I'm sure.The next time when your giving him oral stop & say how am I doing? Do you like the way I suck your d**k?
I love dirty talk. BUT I once had a girl tell me to shut up & keep effin her. It's not like I was having a conversation with her. Then another girl I couldn't get her to stop after I got her started.
Try it he will like it .

I think it depends on the guy. For some guys that is a turn on and some its a turn off. I think you should mention it to him as something you would like to try and see how he feels about it.

Depending on how you tell him.
If you make him think it was his idea, you will most likely get a great response.

Basically you need to show him you are OK with it, and encourage it when he does it on his own.

NO he shouldn't! when you are in the mood kind of whisper it to him in his ear. and I think he should get the clue

The only guys who don't like this are really young guys who have a strange, idealistic view of women.

I'm sure no guy would say anything about you being a slutty person for wanting him to talk dirty. You could try hinting to it by saying dirty things to him first, or being like "does this turn you on?" when you do something. Don't be ashamed to use words you wouldn't always use like "f***" or "cock", or even "pussy". They're all fair game in dirty talk.
