Strap-On: A Guide to Choosing (and Mistakes to Avoid)
The strap-on is one of the most misunderstood toys in our catalog. Some associate it with only one type of couple, others imagine it is extremely complicated to put on, and some buy it looking only at the length, only to discover that the problem was something else entirely.
In reality, it is a simple object, useful for anyone who wants to penetrate without using — or being able to use — their own body. Couples of two women, mixed-sex couples where the woman takes the lead, couples of two men, individuals living with erectile difficulties. The mechanism is the same: a harness that holds a dildo in place.
What changes everything is how you choose the parts.
Harness only or complete kit?
This is the first fork in the road, and almost no one explains it.
The complete kit comes with the harness and dildo already paired. It is the right choice for the first time: you pay less, you don't have to worry about whether the pieces fit together, and you get to try it out and see if you like it.
The harness alone is a belt with a central O-ring into which you insert the dildo of your choice. It costs less than a kit, but it only makes sense if you already have a dildo with a wide suction cup or flared base. A dildo without a base will not stay in the ring: it will slip out.
If you are starting from scratch, get a kit. If you already have toys at home, check to see if they have a flat base: in that case, the harness will save you money. You can find both solutions among our strap-ons and harnesses.
The measurements that really matter
Total length is the least useful piece of information on a product page. Three others are what really count.
- Insertable length. On a 20 cm dildo, the part that actually goes in might be 14 or 15 cm: the rest is the base. This is the number you need to look for.
- Diameter. This parameter determines whether it will be pleasant or uncomfortable, much more so than length. To start, stay under 3.5 cm.
- Weight. A heavy dildo pulls the harness forward and forces you to tighten the straps. Under 300 grams, you can stay comfortable for a long time.
A recurring mistake: buying a large size for your first purchase because "you'll get used to it eventually." The opposite happens — it stays in the drawer, and your money is wasted.
Materials: the rule that saves your toy
Silicone. The best: non-porous, can be sanitized thoroughly, lasts for years. It costs more, and it is worth it.
Jelly, TPE, PVC. Soft and realistic, affordable price. However, these are porous materials: they retain microscopic traces even after washing. They should always be used with a condom and replaced more frequently.
And here is the rule that almost no one writes clearly:
Silicone lubricant on a silicone dildo: never. Silicone dissolves silicone. The surface becomes sticky, turns opaque, and in a few weeks, the toy is ruined. With silicone toys, always use a water-based lubricant.
Silicone lubricant has its place — it lasts much longer and doesn't dry out — but it must be paired with glass, metal, or ABS dildos, or used with a condom in between.
The type of harness
Pant-style. You wear it like underwear; it distributes pressure and doesn't shift. It is the easiest to manage and the most stable.
Adjustable strap-style. More aggressive in appearance, it adapts to any body type and leaves the front exposed — a detail that makes a difference for many people, as it allows for receiving stimulation while wearing it.
Neither is better: it depends on how visible you want it to be and how much you want to feel.
The hollow model
There is a lesser-known and very useful variant: the hollow strap-on, where the dildo is empty on the inside. It is for those who have a penis but not a reliable erection, due to age, medication, or simply because it happens.
It is not a compromise; it is a solution: it is worn over, sensitivity remains, and the encounter continues without having to interrupt anything. If this is your case, also check out our penis sleeves, which solve the same problem in a less bulky way.
The first time: three practical tips
Adjust the harness while dressed. Before anything else, put it on and tighten it calmly in front of a mirror. Doing it on the spot, in a rush, is the best way to kill the mood.
Lubricate more than you think. The person wearing the strap-on feels no resistance or friction: you have to ask, and the person receiving has to speak up. Lubricant is not an extra; it is the missing piece of the communication.
The receiver sets the pace. It seems obvious, but it isn't: without direct sensation, the person wearing it has no way of knowing if they are going too hard. Agree on a signal before you start.
If the destination is anal, a specific lubricant is not optional: the mucosa does not self-lubricate. Check out our anal lubricants, which are thicker and last much longer.
Cleaning and storage
The dildo should be washed with warm water and mild soap after every use, or with a specific cleaner if you are in a hurry. Pure silicone can even withstand boiling water; jelly and TPE cannot, as they will deform.
Fabric or faux-leather harnesses should be cleaned separately with a damp cloth and left to air dry before being put away.
Store pieces separately and keep silicone dildos away from each other: prolonged contact can cause them to react and stain.
In short
- First time: complete kit, not a harness alone
- Look at insertable length and diameter, not total length
- Never use silicone lubricant on silicone
- A condom is mandatory on porous materials and very convenient on all others
- Adjust the harness beforehand, not during
