Why a trainer helps
Practising with a trainer gives you full control. You set the pace, the angle and the depth, you can stop at any moment, and there is no pressure to please anyone. For many adults that sense of control is exactly what lets the gag reflex relax. Our deep throat trainer guide covers what trainers are for, and this article focuses on choosing sizes and moving between them.
What makes a good trainer
Before size, check the basics. A trainer you put in your mouth should be:
- made of body safe, nonporous material, ideally platinum cure silicone, glass or smooth stainless steel
- smooth, with no seams, ridges or rough edges
- fitted with a wide flared base or handle, so it can never slip too far
- easy to hold at an angle with one hand
- free from strong smells, which usually signal a cheaper material
Avoid jelly rubber and anything labeled as a novelty. Porous materials hold bacteria even after washing.
Why graduated sets make sense
Most people do better with a graduated set than with a single trainer. A set gives you several sizes in the same shape, each a little longer and a little wider than the last. Because the shape stays the same, your body only has to adapt to one change at a time.
If you buy single trainers instead, choose them from the same product line so the curve and tip feel familiar. The trainer sets in our shop are curated with this in mind. We never list numbing sprays.
How to choose your starting size
Start smaller than you think you need. The first goal is not depth, it is learning to keep the tip resting on your tongue while you breathe calmly through your nose. A slim trainer, roughly the width of two fingers or less, is a sensible starting point for most beginners.
A useful test is simple: if you feel the first sign of the reflex the moment the tip touches your tongue, the size is right for now and you only need time. If you feel strained, rushed or sore afterwards, go one size down.
When to move up a size
Move up only when the current size feels boring. In practice that means:
- you can hold it at your usual depth for several calm breaths without the reflex building
- you have managed that in at least three or four separate sessions, on different days
- your throat feels completely normal the next morning
- you want to move up, rather than feeling you should
When you change size, go back to a shallower depth for the first sessions. Length and width are both new, so treat it as a fresh start. Some people move up every couple of weeks, others stay with one size for a month or more. Both are fine.
A short routine that works
- Breathe slowly through your nose for a minute before you start.
- Use a generous amount of water based lube. Silicone lube can damage silicone toys.
- Sit upright or lie on your back with your head tilted back slightly, whichever lets your throat feel more open.
- Rest the tip on your tongue, breathe, and move forward only a little at a time.
- Pause the moment the reflex starts to build. Take the trainer out, breathe, and try again more shallowly.
- Stop after five to fifteen minutes, even if it is going well.

How to keep a trainer clean
Clean the trainer before and after every session. Warm water and a mild, unscented soap are enough for silicone, glass and steel. Rinse well, dry with a clean towel and store it in a cloth bag away from other toys, since some materials react with each other.
Check the manufacturer's instructions before boiling or using a dishwasher. Many solid silicone trainers tolerate boiling, but anything with a motor or mixed materials does not. Replace any trainer that shows cracks, tears or a sticky surface. Never share a trainer without cleaning it and, ideally, using a fresh barrier between partners.
Signs you are moving too fast
- soreness that lasts into the next day
- a hoarse voice or pain when swallowing
- any blood, even a trace
- a feeling of dread before sessions
If you notice any of these, take a few days off and return to a smaller size. If a symptom persists, read our article on sore throat after oral sex and see a doctor.
