Oh boy... well, at least it's someone ELSE starting a thread on sex!
'Talking' during sex can fall into several area;
1/ Non-verbal (includes the 'oh god, oh man, oh yeah, oh baby stuff, as well as moans and groans).
Can't help this; it happens. I am (apparently, as it's not as though I listen to myself) in the very loud catagory. I love girls making noise... I went out with one girl who was silent until she came, and then directly afterwards with one who was noisey until she came (and then went completely silent for about thirty seconds... ("Come on baby... BREATHE... Please breathe!"). Very confusing...
2/ Relevent Verbal; the 'raise your leg', 'roll over', 'left a bit' stuff; again, I can't not do that, and like being given feedback.
3/ Added Value Verbal; talking dirty; once I start on this I kinda get on a roll... some girls don't like it, but others seriously love it...I like girls doing it...
4/ Irrelevant Verbal; 'I was saying to my boss... ', 'Oh my, the ceiling needs painting...'; this is vile.
People living in glass paradigms shouldn't throw stones...
