Sex-Lexicon A–Z

Sex is as diverse as the people who live it.

In this Sex-Lexicon you'll find terms, explanations and inspiration around desire, fantasy, closeness, phone sex, role play, preferences and more – understandably explained, without taboos, without judgment.

Many people feel that words are missing when it comes to their desires. This lexicon is exactly for that: so you know terms, can expand your fantasy – and better understand your own sexuality.

You can simply use it as a reference work – or let yourself drift from term to term and discover something new.

And if you feel like not just reading all this, but experiencing it, you can speak anonymously with real people via voice through the SOLO-O App.

Note: This lexicon is informative, not moral. What you want to live from it, you decide yourself – voluntarily, consciously and at your own pace.

BDSM

Short Definition

BDSM stands for dominance, submission, bondage, and pleasurable power play – always voluntary and with clear rules.

  • prior agreement
  • safe word
  • responsibility for each other
