Domme
A domme is a woman who takes the dominant role in a dynamic with a partner, by agreement. On a dating site like this one, she is a member looking for a relationship or an arrangement, not a service she is offering.
Dominatrix
A dominatrix is, for most people who use the word, a professional who provides paid dominance sessions. That is a legitimate line of work and it is not what this site is. Members here are not professionals and do not charge for their time.
Pro domme
Another term for the same paid professional role as dominatrix. If you are looking for that, this is the wrong site, and we would rather say so plainly than let you find out after joining.
Sub
Short for submissive. The partner in the dynamic who takes the submissive role, again by agreement rather than by assumption.
Switch
Someone who takes either the dominant or the submissive role depending on the partner and the situation, rather than being fixed in one.
D/s
Shorthand for a dominant and submissive dynamic between two people.
Femdom
Short for female dominance. Covered in more depth on femdom dating in the UK.
FLR
Female-led relationship. An ongoing relationship in which the woman leads, agreed between both people and often extending beyond a single encounter. Covered on female-led relationships in the UK.
Limits
The things either person has said they will not do. Hard limits do not move. Soft limits might, but only if renegotiated, never assumed.
Safeword
A word agreed in advance that means stop, immediately, no questions asked. Covered properly on limits, safewords and negotiating before anything happens.
