This is the only way I can orgasm. I have to have a directed goal and I have to focus. I cannot orgasm any other way other than with a vibrator, that I have to hold myself, as most of my clitoris was denervated in a clitoral hood reduction performed without my consent during a labiaplasty.
I try to be efficient because all I can let guys do is watch and talk dirty to me. For me, your ideas are completely unrealistic and would lead to me never having an orgasm at all, never being satisfied, and consistently being very angry at my partners (what happens when I feel like I have not gotten my due).
