Seriously though, IMHO, dirty talk is SOOOO Sexy!! It just ads another dimension to what's going on. It has to be done right though.
Too much, too constant and it becomes distracting, like someone babbling on and on during a conversation.
Too "gutteral" and it comes across as vulgar (PSE) which sometimes is cool if I'm in a PSE mood, but mostly I am not; I'm more sensual. I prefer it to sound all silky and naughty like phone-sex, seduction voice. Yum!
Sadly, I haven't been with a lot of Providers that do this (much). And it's not the same if you have to "ask" for it.
(On the flip side, I have to say that it hasn't mattered. Our Providers are SO Sexy and SO Good, when it's not there, I really don't miss it
that much. It's just icing)
Although not the dirtiest, I think my favorite thing (and variations thereof) to hear is, "Yeah, fuck me with that hard dick!"
This does has two affects:
1) It makes me think that my Provider is enjoying it, into it, and wants MORE of it (more effort even - UP that Game!)
2) It re-incourages my Dick to friggin "Man-Up" and "Be All You Can Be!"
