Wow! I have to say thanks to the response... HP, GEL, and Stubborn replying within minutes... it's like the all-stars of this forum! LOL!
Anyway... it's hard to say what her LL is. It seems to change and often makes little difference. Its a moving target. I think it could be the quality/fun activity times. I've tried the process of elimination with no clear success.
The one consistency is passion. She often requests passion. I've tried lots of things that I thought were passionate and I've even asked her to refine and define it for me. Spell it out... hit me with a billboard... only to have the vague response of either "you know... PASSION" or "I dont know exactly..." or just a shrug.
Like I said... she doesnt make a request for ML and has told me she could easily do without it except that she knows that it would not go over well with me. She doesnt even understand that it is not normal or healthy to have zero sex life with your husband.
