What do you mean struggling with her feelings towards women? Exactly how does she plan to "resolve" this?
I mean, if she identifies herself as bisexual then presumably she feels sexual attraction towards women. Where is the struggle in this? Is she saying that she's feeling tempted to stray? I'm assuming that when she got married to you that what she was, in effect, saying was "I am attracted to women but I want to be monogamous to you." Would she agree with that statement?
And the resolution...what sort of resolution could she possibly be talking about? How committed is she to the M?
I'm afraid your post raised more questions than it answered, arj! Also, I agree with Lass that the skin care issues are a smokescreen. But it sure doesn't hurt to do all we can to make ourselves sexually attractive to our mates. What I might suggest is that you start working on the sexual aspect of the R immediately and do it concurrently with the clearing up of whatever skin hangups she has. There's no reason to wait.
Finally, I think counseling pronto would be in order in your case. Set it up and go.
