The Chrono Trainer is a fun device specially designed for men.

It's an automatic masturbator equipped with a back-and-forth counter.

Very easy to use, it provides very intense pleasure thanks to its multiple vibration modes: 8 in total!

The Chrono Trainer works on battery (1h30 of use), and is recharged thanks to the cable provided on a classic telephone charger. Headphones provided allow you, if you plug it in, to hear female encouragement...

Trains you to last longer

The primary purpose of the Chrono Trainer is to train you to last longer. Playful, you can measure your progress thanks to the integrated counter!

Online challenges included!

As a Chrono Trainer user, you will have access to many tips and weekly challenges to train yourself to masturbate longer and longer. This is why the Chrono Trainer can contribute to slower ejaculation during sexual intercourse.

Why the Chrono Trainer?

Don't be ashamed of your performance

Man is biologically designed to ejaculate quickly. It's not a disease, it's a reminder that ejaculatory function is for reproduction, not sexual fulfillment. While we're not all born equal when it comes to self-control and pleasure, it's not that hard to learn how to last longer, although that's a very subjective notion.

It's a welcome help

The Chrono Trainer and its exercises aim to help you master your ejaculatory reflex. Its particularity comes from the fact of not limiting its use to simple masturbatory exercises.

To have fun...

Indeed, the Chrono Trainer can bring you A LOT of pleasure, simulating many types of fellatio, each more exciting than the other. Its back-and-forth counter encourages you to always surpass yourself, and to measure your progress. You make your MIND work.

You will also have access to a protected online space:

  • with tutorials and training tips to improve yourself
  • a scorecard, to keep track of your progress
The advice provided prepares you physically to use the tricks your muscles offer you to delay the onset of ejaculation. You make your PHYSICS work.

Outdo yourself!

The best way to see your progress and never lose your motivation, is to remember to write down your score. This differs depending on the Mode you have chosen. You will find your score cards on the user guide supplied with your Chrono Trainer.

Good idea for premature ejaculation

The concept is well thought out, and the challenges included are as fun as they are useful. I don't regret my purchase.
