I’ve seen some hypnotherapy done for anorgasmia, and it seems a little like this. One of the standard techniques is to mentally link up an innocuous point on the skin to the idea of genital stimulation when the subject triggers their own post hypnotic suggestion. The one I saw was on the back of the hand. I think the idea is if lubrication isn’t happening and intercourse is painful, the linked point can act like a primer pump for them to rub to get worked up enough for the real fun. Though a few demos I saw could seemingly stimulate an orgasm (I say seemingly because hypnosis all about trust and playing a part, and hopefully the placebo effect can kick in and help with psychosomatic problems).
