A rear approach sexual technique which involves the male partner’s penis being placed between the female partner’s bottom cheeks, after which he slides up and down until orgasm is achieved. This style of sexual intimacy avoids penetration, allowing virginity to be preserved, but the proximity of the penis to the vagina, with the obvious chance of ‘trickle down’ means that contraceptive precautions must be taken to reduce that risk. The technique is very unlikely to provide sexual satisfaction for the female partner unless direct clitoral stimulation is provided by either partner. Lubrication is essential to avoid discomfort for either partner and to ensure that ejaculation can be reached in an environment which is as viscous (slippery) as vaginal or oral intercourse.
