For what it's worth, most of the time I'm very alpha----I sold another bunch of paintings Friday, made a huge new business deal today at lunch, I'm successful and confident....I just can't deal with a sexless marriage very well at all.
I never did figure it out, Grey, which is probably why you should probably throw out all of *my* advice as the low test score here, and just accept my heartfelt empathy.
You have to decide how important this one aspect of your marriage is to you, and whether it's a dealbreaker or not. For me, I ultimately decided that it wasn't, I let it go, and I've never been happier. You sound like you may not be "there" yet, and THAT IS OK. You have a right to want what you want.
