Pegging is the sexual act where a woman uses a strap on to anally penetrate their male partner. As with so many sexual acts out there, any couple can try it, as long as they are willing to, wink*.
Ideally, the woman will use a harness compatible dildo made out of silicone; some couples decide to first try it out with just a dildo, but pegging, by nature, refers to a woman penetrating a man, so a harness is necessary. Also, you will need plenty of lube as with any other anal practice in order to make things easier and more enjoyable.
As for the type of harness, it will depend solely on preferences; you can use a g-string style or boyleg. For the dildo, it will also depend on what the man prefers and what size are they comfortable with. The dildo can be something very realistic or maybe something less realistic but with extra cool things that make the experience a bit more fun…it will be a matter of taste and preferences.
Pegging is highly stimulating practice for men because the equivalent of the female g-spot, called p-spot, is located near the prostate and inside the rectum. Besides of the physical aspect, some men also enjoy the psychological aspect of being penetrated and taking a more submissive role in sex as well.
If you’re thinking “ok, great for the man, but what do women get out of it?” well, some women simply enjoy the sensation of penetrating their partner. Usually it has something to do with that power reversal and the feeling they are the ones dominating instead of the other way around that happens with vaginal sex. On the other hand, women also like seeing their partner enjoying himself, kind of like when you orally pleasure your partner; you enjoy giving pleasure to your partner. If you want an extra reason, there are some double-ended dildos you can use together with the harness, so the woman can also enjoy penetration while they are penetrating as well. Win-win for all.
