lee, We should probably take this to a new thread but you just described my W. My W is completely out of control and uninhibited when she is drunk but just the opposite in sober life. This leads me to assume a few things...
1. She, like you said might simply be using sex as a "self-control" point. 2. She's possibly scared of her sexuality and fearful that she will be less virtuous in her own eyes. 3. She simply gets crazy when she drinks.
At any rate, I've been thinking about talking to her about it BUT I have to keep reminding myself that her sexuality (and brain) is hers and all I'm allowed to care about is how it touches me. Sure, it would be really cool to have a counsellor untap that part of her and have her turn into a sex maniac. But right now, I just need focus on the fact that she's struggling to meet my desires, appreciate her for the progress she's made in meeting my desires. She's becoming a lot more relaxed these days with the idea of ML which is huge.
