In This Guide
First times with a strap on are often better than people expect — and sometimes more awkward than they expect. Both things are fine. This guide is practical and honest: what to do, in what order, and what to do when something doesn't go perfectly.
Before any equipment: talk to your partner about what you both want to try, what you're nervous about, and what your signals are if something isn't working. A good first experience starts before you open the packaging.
What you'll need
- A strap on harness (adjustable) and a compatible dildo, or an all-in-one set
- Water-based lubricant — more than you think you'll need
- A flat surface and about 10 minutes to fit the harness before you're in the moment
- Clean hands throughout
- A towel nearby
Before you start: communication
This might seem obvious, but it's the part most people skip or rush. Before you start:
- Agree on a specific signal to pause or stop — a word, a hand signal, whatever feels natural
- Discuss what the receiving partner wants to try and what they'd like to avoid
- Agree that awkwardness is expected and not a failure — first times are a calibration exercise
- Confirm lube preferences — some people have sensitivities to certain lubes
Fitting the harness
Fit the harness before you're in a sexual context. Standing in front of a mirror with your clothes on is ideal. The harness should:
- Sit snugly against your pubic mound — not your stomach or lower on your thighs
- Feel stable when you move your hips — no shifting or riding up
- Be adjusted so all straps are symmetric — an off-center harness causes the dildo to point awkwardly
- Not dig into your skin uncomfortably — padding or fabric harnesses help if the straps irritate
Insert the dildo into the O-ring before adjusting the final fit. The dildo should point slightly upward when the harness is correctly positioned — this helps with penetration angle during sex.
Lube — more than you think
Strap on sex requires more lube than most people expect, for two reasons: a dildo doesn't self-lubricate the way a biological penis might, and a dildo doesn't provide the wearer biofeedback about friction — so it's easy to not notice when the partner needs more.
Apply lube generously to the dildo before penetration and reapply during if there's any sign of friction or discomfort. Water-based lube is safe with all silicone dildos and harnesses.
Step-by-step: your first time
Starting positions
Receiving partner on top
Best first-time position. Receiving partner controls depth and pace entirely. Wearer lies flat. No thrust required from the wearer.
Missionary
Familiar position, but requires the wearer to manage angle carefully. Works well once both partners have calibrated with the on-top position first.
From behind
Good for deeper penetration once both partners are comfortable. Gives the wearer more movement control. Works for vaginal or anal use.
After
Remove the harness and dildo and clean both. Most fabric harnesses go on a gentle machine wash cycle. Silicone dildos wash with soap and water. Talk briefly about what worked well and what you'd adjust — this information makes the next time better.
Most couples find the second and third time significantly smoother than the first. The harness becomes familiar, the lube routine becomes automatic, and the communication gets more shorthand. Don't judge the experience entirely on the first attempt.
FAQ
How long does it take to fit the harness?
The first time: 5–10 minutes. Once you know your sizing, most harnesses can be stepped into and adjusted in under two minutes.
What if the dildo shifts during sex?
The harness isn't adjusted tightly enough, or the O-ring is too large for the dildo base. Adjust harness straps to be snugger, or try a dildo with a larger flange base.
Can I wear the harness under clothes?
Yes — thong-style harnesses and brief-style harnesses are designed for this. A useful way to feel comfortable in the harness before a sexual encounter.
What if it hurts the receiving partner?
Stop and apply more lube. Check the angle — a dildo angled straight instead of slightly upward can cause discomfort. If discomfort continues, try a smaller dildo size.
