Dildos & strap-ons
Strap-on harnesses: the ring size matters more than the straps
A harness has one job: to hold a toy where your hips put it. Almost every failure is a ring that is the wrong size, or a strap tightened to compensate for a harness that does not fit.
A harness is a waistband, a front panel and a way of holding a toy. Everything else is a variation on how the panel is held against the body and how the load is spread. The load is real: a toy worn on the pubic bone acts as a lever, and the harness has to resist it without being strapped tight enough to numb a leg.
Two measurements decide whether a given harness works for you, and neither of them is the size on the label.
The two measurements that decide it
- The ring diameter against the base of your toy. The ring must be smaller than the widest part of the base and larger than the shaft just above it. Too wide and the toy pulls through; too narrow and it will not seat at all. This is why harnesses that ship with three interchangeable rings are worth more than harnesses with a better buckle.
- Your own measurement, at the hips and not the waist. A harness sits on the hip bones, not the natural waist, and the circumference there is often several centimetres larger. Harness sizing is where people most often buy a size down and then blame the product for digging in.
The four styles, and what each one is good at
- Two-strap. A triangle panel with a strap around each thigh. The thigh straps take the lever load, which makes this the most stable style for vigorous use, and it leaves the wearer uncovered, which some people want and some do not.
- Jock, or one-strap. A waistband with a single strap between the legs. Quicker to put on and less adjustable; the single strap also sits exactly where it can be in the way for a wearer who wants their own stimulation.
- Briefs or boxer style. The panel is built into a garment. The most comfortable style to wear for a long time and the easiest to put on in the dark, at the cost of being a fixed size: there is far less adjustment than a strap harness gives.
- Thigh harness. A panel strapped around one thigh. A completely different geometry, useful for angles that hips cannot reach and for anyone whose hips or back make a conventional harness painful.
Fitting one so that it stays put
Seat the toy before you put the harness on
Push the base through the ring from the inside and work it round rather than forcing one side. A base forced through on one edge is how O-rings tear.
Set the waistband on the hip bones
Not the waist. Tighten until it stays without being pulled, then stop. The waistband is a position, not the thing taking the load.
Tighten the leg straps last, and evenly
Those straps are what stop the toy tipping. Even tension on both sides is what keeps the toy pointing where you aimed it.
Check the angle standing up and kneeling
The angle changes with posture more than people expect. Adjust in the position you plan to use, and expect to redo it once more after the first few minutes.
Add a cushion between the panel and the body
A folded flannel or a dedicated pad behind the base removes almost all of the pressure that makes a harness uncomfortable at the pubic bone. It is the cheapest upgrade in the category.
Reading a harness listing
- A stated ring diameter, or better, several rings included. If the listing gives no ring measurement, you cannot know whether your toy will seat.
- The adjustment range in centimetres. Harness sizing by small, medium and large tells you nothing. A range does.
- A washable material. Nylon webbing and silicone-backed fabric wash. Leather does not, and glued seams come apart in a machine.
- Hardware that is metal, not moulded plastic. The buckles and sliders take the whole load. Plastic sliders are where cheap harnesses give way, usually mid-use.
- Whether it accommodates a vibrator pocket. If the wearer wants their own sensation, this is the feature to look for, and it has to be stated: a pocket cannot be added later.
Questions people ask
- Can any dildo go in any harness?
- Only ones with a flared base wider than the ring. A suction-cup base usually works because the cup is wide; a tapered base or a base with a vibrator cap often does not.
- Which style is most stable?
- Two-strap, because the thigh straps resist the toy tipping. Briefs are the most comfortable and the least adjustable. That trade is the real choice in this category.
- Does the wearer feel anything?
- Not from the toy itself, which is rigid and transmits very little. Harnesses with a vibrator pocket or a double-ended design exist precisely because the plain arrangement gives the wearer pressure and nothing else.
- How do I wash it?
- Nylon webbing can usually be hand-washed and air-dried; check whether the maker allows a machine. Leather is wiped only, which is why it is a poor choice for a harness used by more than one person.
