Mike I think Lassie is doing a fine job, so I will leave it to her.
I really have no experience at being LD and then HD. I have always been HD, through pregnancy, childbirth and long term nursing of (so far) two kids. So the "usual" culprits have not turned me off.
So I'm not sure I really have much to add to the convo, as far as what to tell an LD wife to get her motivated to meet her H halfway. I know that I have been utterly unsuccessful at convincing my LD SIL that she would be a lot happier with a better sex life, and to stop thinking about it in terms of her husband "winning" the battle.
Probably the only thing I would stress is that frequent sex will make HER happier, forget about the guy.
And then I'd (hopefully) make her toes curl with stories of my (mostly) happy sex life with H. I would love to do that with SIL but she is H's sister and TMI would prolly gross her out.
I do know that I'd stay away from the 'he feels rejected and lonely' slant, as it doesn't seem to matter. When you are dealing with that level of resentment, they don't care what he is going through. It sounds harsh but hey, I've been there (resentful) about other topics--not sex--and I didn't care what he was going thru.
Lass, would the knowledge about how much your H was suffering have helped you overcome your LD when you were in that position? If it would have, then I stand corrected.
Oh well, as I said, I'm not sure what I would say since I have always been HD and have even ended a long term relationship because of too little sex, before I met H. So half the time I wonder if I am the problemo.
