This practice is done by masturbating yourselves together or having hand sex with one another. This kind of partnered solo play can happen in the same room, via video, or even on the phone if you’re shy or just enjoy some hot aural sex (sex sounds).

How mutual masturbation works in relationships

It’s pretty much the most intimate thing you can do with a partner.

You’re letting them watch and listen as you do something that most people only do behind closed doors.

It can make you feel an exciting — and kind of terrifying — mix of vulnerable and powerful at the same time.

As for them, being privy to the peep show and watching you pleasure yourself can kick up the naughty factor by a bazillion.

Other reasons it’s awesome: Pleasure’s a sure thing, because each of you gets to do what you already know feels good for you. You get to release your inner voyeurs and exhibitionists at the same time. (You know they’re in there!)

It’s the best sex ed you can get, because your lover gets to learn how to give you pleasure from the most qualified instructor: you. And vice versa. If you want to introduce sex toys into the bedroom, this is hands-down the best way to start the convo.

It’s totally versatile and can be used to fulfill other fantasies, like role-playing, threesomes, or group sex.
