I dated a girl, in college, who totally got off, on me going *really* slow. In and out, though. I got to where I could have an orgasm like that too. It was like having sex, in slow motion. I would picture two claymation figures, going at it.... e-v-e-n-t-u-a-l-l-y.
I thought "I bet this is how retarded people do it."
She could really feel it when I came though. For that matter, so could I. She would grip me so tight, with her muscles, it was intense. She's the only one I ever did that with. I'd put my elbows above her shoulders and go super slow, the last inch or two and then pushpushpush, without pulling back.
