I disagree with this. Why?
Because I've always been high drive no matter what the state of my relationship is. Most of the women I know are the same, they love sex and want lots of it.
Not everyone is like you and your friends. I agree with her.
I compare libido to a muscle you can exercise. Some women like you have a libido like a heart muscle. As long as you live there is a steady, strong pulse of sexual drive throughout your being. I have always been impressed with people like you.
You could improve just like a heart could be in better shape but unless you are dead, that sex pulse never stops surging.
My wife has a libido like skeletal muscle. It is there and works but if neglected or unused, becomes atrophied .
If, however, she puts good nutrients in, exercises and uses the muscle often, HOT TIMES!!!
I think my libido is like skeletal muscle as well, just one that has been very developed to the point that it will never fall that low.
My libido has not been steady through my life.
