Sometimes, and with some women, the challenge of helping them build an orgasm is even more pleasurable than the penetration itself, not always, but there were several of those in my life. I got out of that with a tremendous boost in my self esteem. It was always somebody I was in love with, so, no, not on casual sex, no. It required a deep connection, a deep care for their pleasure, for their well being, way above my own, and it ended up to be some of the most memorable orgasms of my life.
Don't mind me, I'm weird, I know.
Peace
