Do I have to be in a relationship or married to join?
No! Because this is all about YOU. Your body, your sexuality, your pleasure. This is for you regardless of your relationship status. If you're single, it's your chance to really know yourself intimately before getting into a relationship. If you're coupled up, this will feed your relationship.
Is this only for women?
Yes. This is a community just for women, and female-identified. Sorry blokes, you are wonderful, but this is a space for women to find themselves again.
