It's not that they don't feel anything at all, but that they can't be satisfied because they don't have the sensation of "climaxing"... The number of women like this is increasing. There is a gynecologic clinic that solves such problems. The treatment there is to have patients who have lost their sensitivity for some reason perform sumata (intercrural sex) to awaken the sexual sensations that lie dormant deep inside. Can patients who have their sensitivity increased by sumata (intercrural sex) resist the temptation of penetration?
