Anal training isn’t about forcing your body to stretch. It’s about teaching it to relax. Knowing a little about what’s happening makes the whole process less mysterious, and a good deal more comfortable.
Two muscles, two kinds of control
The anal canal is a short passage, roughly three to four centimetres long, surrounded by two rings of muscle.
- The internal sphincter works automatically. You can’t tighten or relax it on purpose.
- The external sphincter is under your control. It’s the muscle you squeeze when you’re holding on until you reach a bathroom.
Both are designed to keep things closed. That’s why a quick or unexpected stretch makes them clench, and why going slowly matters.
Why slow, steady pressure works
The internal sphincter has a built-in reflex that lets it relax in response to steady pressure. Rushing tends to trigger the opposite: a protective clench from the external sphincter. Slow insertion, deep breathing and plenty of lube give that reflex time to work, and help you consciously let go of the muscle you do control.
What actually changes with training
Most of the change is in how your body responds. With repetition you learn to relax the external sphincter deliberately, your nerves get used to the sensation of fullness, and what once felt intense starts to feel familiar, and often pleasurable.
That’s why small steps work. Each new size is only a little more than your body already knows, so the response is “this is fine” rather than “this is too much”.
Your nerves and your brain
The area is rich in nerve endings, which is a large part of why anal play can feel so good. It also means your body notices tension quickly. Anxiety tightens muscles; feeling safe and relaxed loosens them. Breathing slowly and taking your time aren’t extras. They’re part of the technique.
Lube isn’t optional
Unlike the vagina, the anus doesn’t produce its own lubrication, and its lining is delicate. Generous water-based lube reduces friction and the chance of small tears. Reapply as often as you need to.
How Slo.Mo is designed around this
- Seven small steps. The Peak grows by 3.5 mm at the first step and by 2 mm at the last, because a millimetre is felt more the larger you go. In proportion, the increases reduce from 13% to 5%.
- A Peak and a Valley. Easing over the Peak and back is the stretch that trains. The Valley is where your muscles rest and relax.
- A familiar start. Each new plug’s Valley is narrower than the Peak you’ve just mastered.
- Softer at the top. Plugs 5 to 7 are cast in a softer silicone, so the largest sizes stay comfortable.
Slo.Mo by Pace
Designed around how the body adapts
Seven solid silicone plugs, each a measured step up from the last, with increases that reduce from 13% to 5% as the sizes grow. A Peak to train on and a Valley to rest in, a number engraved in every base, and silicone independently tested by SGS. A$230, with complimentary express shipping in plain packaging.
Three common myths
- “It has to hurt at first.” It shouldn’t. Pressure and fullness are normal; pain is a signal to slow down or stop.
- “You need to clean out completely first.” A shower and a bathroom visit is enough for most people. Douching is optional.
- “The goal is the biggest size.” The goal is whatever feels good to you. Plenty of people stop part-way through a kit.
When to see a doctor
See a doctor if you have pain that doesn’t settle or bleeding that doesn’t stop, or before you start if you have haemorrhoids, a fissure or inflammatory bowel disease, or are recovering from surgery in the area. Slo.Mo isn’t a medical device and isn’t intended to diagnose or treat any condition.
