I have already thought of lack of progesterone as she has been on the pill for years to regulate her irregular cycles. And I have already tried to suggest that maybe she has an imbalance of hormones. But, she does not agree.
This is probably it. It's not a lack of progesterone but a lack of testosterone. I was on the pill for over a decade and it can indeed kill your testosterone levels. When I went off the pill I definitely noticed an increase in desire (which totally sucked because it was in the middle of BF's A and I was not getting or giving any). Now that I have an IUD with hormones I noticed that the desire level has gone way back down again.
The only way to know for sure is if she has her hormone levels checked by a doctor. It certainly never occured to me that something was wrong because it was the only way I remembered being with BF once the initial falling in love phase had passed.
You can't make her go to the doctor. You can tell her that it is a dealbreaker for you and that if things don't improve in that area then you will both be better off finding someone who fulfills your respective needs.
When my BF dropped the bomb, our dismal sex life was one of the things he complained about. I immediately started reading SSM and went to the doctor to get checked out because saving the R was important to me. If your W does not check out every avenue then I think that's telling.
BTW, the pill affecting a woman's sex drive is becoming much more publicized these days so you should be able to find articles about it. My local news just did a story on it earlier this week.
