DEAR ABBY: I’m in an open relationship with my partner. We both enjoy hooking up with other people, but only if we agree on the person. It was going great; I still got my one-on-one time with my partner. But now it seems that instead of making love with just me, the only time he wants to touch me is if someone else comes over. What’s the best way to approach him about it? Should I suggest we stop inviting people over for that type of fun? -- ADVENTUROUS LADY
