And, (and at the risk of making myself sound like a total slut), I've been in relationships with good sex, great sex, and rock-my-world sex.
All I'm trying to say is that -- if the underlying issue is the sex itself (and, of course, it isn't in every case) that no amount of quality time, conversation, chores, words of admiration, or emotional connectness is going to fix it.
btw: freezer guy called and said he'd love to see me this week. Especially if I was wearing black thigh-highs and, um, going commando. He also said he'd bring a couple of extra ties......
