As with all Theros products, you can enjoy extraordinary erotic experiences with our FMS dilators — solo or with a partner — that will enrich your erotic world.

Our dilators differ from conventional glass dilators, glass dildos or similar sex toys in that you can tailor the size(s) precisely to your bodies and to how you want to use them. We provide tips on how to determine the right sizes.

The smooth, frictionless surface enables an exceptionally gentle application, and the unique glide opens up new erotic perspectives.

Facing vaginismus together

With vaginismus or dyspareunia, after injuries in the genital area or after a long period of abstinence from sex/intercourse, you can gently use several increasing sizes together for “opening” and getting used to penetration. The prerequisite is that, as a woman, vaginal penetration by your partner is truly your own, authentic wish.

Exploring boundaries — gently

The finely graded recommendations for our dilator sets are also suitable for more intense practices; sizes can then be significantly larger — exactly as you both enjoy and as it enriches your shared experience. This way you can explore breathtaking boundaries together in a responsible way — without the risk of injury.

Temperature as a muscle relaxant

FMS dilators are hollow and — the larger they are — the better they can be kept warm for longer by filling them with water-soaked tissue (e.g. kitchen paper) and bringing them to a high yet body-safe temperature in a controlled manner. An adjustable baby food warmer is ideal. The tissue reliably prevents moisture from escaping.

Higher temperature is an excellent muscle relaxant — it deeply relaxes and works almost instantly on contact. Intense warmth is also erotically stimulating — a wonderful combination …

Switch the roles – ignite your souls

You consider yourselves a “typical” heterosexual couple, yet your sex life feels bland and routine, with fixed roles — just like in everyday life, clearly split into male/female?

According to C. G. Jung, we all consist of many archetypal facets that make up our overall personality. That alone opens up worlds of erotic creativity — and, even more importantly:

No man consists only of the masculine pole, and no woman only of the feminine pole.

All people carry both poles in different proportions. The goal is to activate both opposites so that life energy can flow optimally. Sexual role reversal is a wonderful way to achieve this and enrich your entire experience.

The woman takes over penetration (perhaps for the first time) — becoming the active part, in line with the masculine symbol of the arrow.

The man (perhaps for the first time) allows himself to be penetrated and thus takes on the enclosing part (“circclusion”) — becoming the receptive, passive pole, in line with the feminine symbol of the circle. Often, activating this “second”, feminine pole is what allows full masculinity to unfold.

Role reversal often helps with potency issues — also thanks to the prostate massage that occurs in the process.

This game first calls for openness and genuine care, then good preparation (size selection) and, above all, mindful execution. You can start with manual use of dilators in a setting you both prepare together: the man more passive, the woman more active. It becomes even more realistic when the woman uses the dilators (alternating) in a suitable strap-on. We’ll cover this in more detail in our sex guides.

Role reversal is, of course, also a powerful way for homosexual couples to break up monotony caused by rigid role patterns in sexuality and relationships.

As a (re)activation of the opposite pole, role reversal not only creates an erotic, “thrilling rush”: practised mindfully as an erotic-spiritual exercise, it also has an effect on everyday awareness and enriches your entire lived experience — for each of you and for you as a couple.
