Back and forth dildo: how to choose a suitable model?

A back and forth dildo is a sex toy designed to automatically reproduce a penetration movement. Depending on the model, it can associate this movement with vibrations, rotations or several adjustable speeds.

The main interest is to enjoy a regular rhythm without having to move the toy by hand.

Choose the right size

The dimensions must be chosen according to your experience and especially your comfort. For starters, a moderate diameter and progressive shape are generally easier to use than a very wide model.

There is no need to respect a specific category in millimeters. The flexibility, shape and quantity of lubricant influence both comfort and the announced diameter.

Choose the right size

Users accustomed to penetration may prefer more circumference for a filling sensation, but the pain should never be considered a normal step.

What material?

Quality silicone is usually a good choice for the part in contact with the body: it offers a smooth, easy to clean and pleasant to the touch surface.

TPE is more flexible, but requires more drying and maintenance precautions. For materials whose composition is not clearly indicated, it is better to avoid products intended for prolonged insertion.

Manual or motorized?

Manual or motorized?

A manual dildo lets you fully control the angle, depth and speed. It is silent, simple and requires no recharge.

A motorized model adds automatic movements. Before first use, test the speeds in your hand to understand the actual amplitude of the mechanism. Then start at the slowest level.

Suction cup and stability

Many models have a suction cup for hands-free use. Attach it only to a smooth, clean and stable surface, then pull the toy lightly to make sure it does not come off.

With a back-and-forth machine or mechanism, stability is even more important: the movement should never push the toy uncontrolled.

Tips before use

Apply water-based lubricant to the toy and intimate area. Introduce it gradually and adjust the speed only when penetration remains comfortable.

After the session, clean the insertable part according to the manufacturer's recommendations and let it dry completely before storage.

The best back and forth dildo is therefore not the biggest or the one that has the most modes: it is the one whose size, material and movement really correspond to the sensations you are looking for.
