I'm in a fantastic open relationship. I love my girlfriend very much, and we both love fucking other people very much. Just as a personal moral thing, however, I really want any girl I hook up with to know that I am emotionally spoken for, so where along the course of the night would you mention this? If I'm just getting a number, is that something I should tell her before we stop talking? Can that be said over text? I've only had to deal with this once so far, and I told her as the evening we met was coming to a close. She was okay with it, but it definitely killed the chemistry a bit.
