And it doesn’t have to be erotic — it just happened to be that way for me. Boundaries can be anything – boundaries of desire, boundaries of fantasy, boundaries of closeness or separation. Sometimes a person discovers this on their own, sometimes with a partner, sometimes in a group. This is a very individual matter and not for everyone. Some people simply need to define their limits, while others aren’t interested in doing so. Both approaches are completely normal. And it’s okay to talk about it too. Besides, it’s interesting.
