I can orgasm with 2 fingers at my gspot while i stimulate my clit, but when he's inside i find that it stretches me so much girth-wise that its hard for me to concentrate on anything my clitoris is feeling. I've managed to a handful of times wear myself out with my vibrator in a strategic position while he was thrusting. While the orgasm was sooooo much more intense, it was a hell of a lot more frustrating and exhausting to ever get to.

I only try it a couple of times a year. All the grinding and depth in the world can't make some of us orgasm. There's a lot of psychophysiological reasons why. I have a very tiny, although in working order, clit and i dont think it gets much friction or pressure from sex.
