The peg position is a penetrative position involving both partners laying on their sides with their heads in opposite directions.
The penetrating partner lies between the legs of the receptive partner and holds their hips or buttocks. The receptive partner can wrap their arms around the penetrative partner’s legs. The peg position is used for both vaginal and anal penetration.
The receiving partner lays on their side in the fetal position and opens up their legs. With their head pointing in the opposite direction of their partner's head, the penetrating partner lies between the open legs for penetration. "
The tangled-up nature of the position allows for a significant amount of skin-to-skin contact, including touching some less frequently explored erogenous zones such as the knees, calves, feet, lower back, and hips.
The main benefits of the peg sex position are that it is a very comfortable position, with both partners on their sides and not having to exert power to hold themselves up. It may look complicated at first glance. However, once both partners become used to moving into the peg position and aligning their bodies, it does provide a very natural fit. At the same time, the peg position allows for deep penetration. Considered a rear entry and a side position, the peg position allows both partners to control the penetration depth together or individually.
The receptive partner can stroke the penetrating partner’s penis or strap-on up and down with their vagina or anus, or the penetrating partner can thrust with ease. Another method would have both partners contracting their buttocks muscles to grind into each other simultaneously. This position also makes the receptive partner’s anus available for additional stimulation, including possible double penetration. Anally inserted fingers or sex toys would add extra pressure on the wall that borders the vagina and anal cavity. Penetration can be achieved with a penis or a strap-on dildo, making this position possible for people of all genders and sexualities. Couples of very different heights will find that the peg position allows for new sensations and stimulation.
