Re: too much libido
Daina, your husband is wrong to call you "walking hormone". I would give anything to have my wife be like you! I think it's a gift to have a high sex drive -- the only problem is you pay a price when your partner can't keep up with you!
It's pretty common for people to appear to be sexually matched at the beginning of the relationship when the novelty and excitement are high. But when things settle down, the person with the higher biological drive stays high, while the other person drops farther down.
How can I convince you not to try any kind of surgery or method for reducing your libido, certainly not in any permanent way? Let me try by saying that if I were to divorce now and look for another woman, one of the most important qualities would be that she have a high sex drive, with a sustained history of being high, not just flash-in-the pan at the beginning of a relationship. I know that sounds crass, but after what I've been through, the last thing I want is another relationship with a low-libido woman, no matter how positive everything else is. I already have many positive things with my current wife, so it would make no sense to find someone else where that quality wasn't substantially different.
That's in sharp contrast to what I looked for in a woman when I met my wife. I figured the sex would take care of itself if two people loved each other and seemed somewhat sexually matched at first. Dumb assumption.
And as for your husband being 40, that's not a sufficient explanation for lack of interest. I'm in my late 50's, and I would like to have sex about 5-10 times a week. And I'm sure I'm not alone among men in their 40's and 50's, never mind 30's!
If you go ahead with your plan to reduce your libido, all I can say is, aya ya ya, what a waste! Many of us men dream of women like you -- just the way you are now!
