I know it's something that works perfectly well for a lot of people, but I think it would bother me. I don't think I would feel valued, or like I was meeting my partner's needs, if he wanted to see other people. I know that's not necessarily what it means, but I don't think it would ever feel right to me.
Should I take that to mean that it's not as important to you, but it's a concession you don't mind making?
