You put on the harness, catch yourself in the mirror and discover an unexpected amount of confidence. Then a strap slips and you remember you're still learning where everything goes. Both can be part of your first strap-on. Looking hot and needing a quick adjustment aren't mutually exclusive.
A basic strap-on has a harness you wear and a dildo it holds. Start with a harness that fits your body and a dildo the receiving partner actually wants to try. The biggest one in the shop can mind its own bloody business.
Choose a harness that stays where you put it
Adjustable strap harnesses let you tighten the waist and leg straps separately. Underwear-style harnesses feel more like pulling on briefs, with less fastening to deal with. Neither style is automatically better. Think about what you'd be comfortable moving around in.
A secure fit means the dildo moves with you instead of wobbling off on its own little outing. You should be able to bend and shift without straps digging in or the waistband slipping.
Our strap-on harness guide goes deeper into the fit differences. Measure where the harness will sit before buying, because “adjustable” still has a size range.
The dildo and harness need to fit together
With a common O-ring harness, the dildo's shaft goes through the ring and its wider base stays behind it. The base stops the dildo pulling through. It's the shaft just above that base that needs to fit the opening securely.
Some harnesses have interchangeable rings, while others use a fixed opening or a different attachment. A compatible set can make your first purchase easier. If you're buying separately, match the dildo to that attachment rather than assuming every toy with a wide base will fit.
Browse our strap-on dildos with both the harness and the receiving partner in mind. You're choosing something for two bodies, even though only one wears it.
Pick a size you both want to handle
The receiver might love a modest size and a smooth shape. The wearer might prefer a lighter dildo while getting used to controlling it. Those are useful preferences, not reasons to buy a more impressive-looking cock.
Length, width and firmness all change how a dildo feels. A long, heavy toy also puts more pull on the harness. Starting with a manageable size leaves you free to learn the movement without wrestling the purchase.
Sort the straps before you're distracted
Try the harness on with the dildo attached before partnered play. Move around, tighten anything loose and notice whether you can reach the buckles comfortably. A little preparation saves a lot of naked frowning.
When you're ready together, use water-based lube, start slowly and let the receiving partner guide what feels comfortable. Stop for pain. Our first-time strap-on positions offer supported ways to get used to it.
Clean both parts afterwards
Detach and clean the dildo, then clean the harness using the method suited to its material. Washable fabric and leather need different care. Let both dry fully before putting them away, and clean the toy or change its condom before switching people or going from anal to vaginal use.
Next time, you'll already know which strap goes where. Then you can give that confident look in the mirror a little more of your attention.
