You can try with sensate focus. This is a type of sex therapy that you and your partner do together. It starts with you both agreeing not to have sex for a number of weeks or months. During this time, you can still touch each other, but not in the genital area (or a woman s breasts). The idea is to explore your bodies, knowing that you will not have sex. After the agreed period of time, you gradually start touching each other s genital areas, which should eventually build up to penetrative sex 6.
