you know you like strap-on / pegging play, then I'd say yes, it's a GREAT harness. After you adjust it the first time, it's super easy, quick, and comfortable to wear. Also, it holds small or medium dildos VERY securely. And it's easy to take care of.
If you're not sure whether you'll like strap-on play, you might start with something less expensive (we just got the Adjustable strap on dildo harness and it's pretty good for about half the price of the Joque). But if you know you like strap-on sex and that you'll keep doing it, I HIGHLY recommend the Joque.
