My partner is average size (about 5 inches), I can only orgasm if we have sex in certain positions, on my back and legs up near my shoulders, or where he can penetrate me more deeply, accompanied by clitoral play.
I suppose it would be interesting if I was a bit fuller, whether it would make a difference to my orgasm. I’ve never had sex with a well-endowed man, does it make a difference to those who have?
