I have to disagree that a woman having a low libido always means that things are "on the rocks".
I have an extremely low libido, honestly-I haven't "wanted" any in well over 7 years. Seriously. I am completely content with hand holding, cuddling, talking, and all of those intimate things.
I don't know why my libido is so low...it just is, and has been for as long as I can remember. My libido started getting low when I was around 20 years old or so...so given the age when I started becoming active in that way-I only had a couple good years.
I just don't desire it. It has nothing, in my case, to do with my husband. He is attractive, funny, I think he is sexy, adorable, and we are best friends. I find him attractive-and am affectionate to him as far as coming up behind him and hugging and smooching on him-I just have no desire for it to go further than that. I had relationships before my husband-and it was the same way-so it has nothing to do with whether I am happy with my partner or not.
I guess I just feel love in different ways-and sex isn't one of them. I would go to the end of the earth for my husband...and I am always making him things, giving him little presents and notes/cards...and otherwise showing love-but I just have no desire in the sexual area. None.
It feels like a chore-and I actually feel at times like when it does happen, that it is taking time away from me that I could be doing something more productive/enjoyable with-such as reading, SLEEPING, a chore that needs to be done, etc.
It is absolutely AMAZING that we have the last two out of our three children-but they were both conceived on the first try-amazingly enough.
There are lots of women, and men, who have similar problems.
