What contributes to a low libido?

I have seen my physician several times to find out why my libido has diminished. Well, maybe as I get older, it could be the result of menopause. But I recently read an article that talked about relaxing more in a stressful world. I think that is true. If I take away the stressors in my life with work and everyday issues, I think it is easier to be more interested in intimacy. There are so many ways to combat physical issues when one gets older such as medications, etc. But stress can easily play a role in one’s libido. Making time for intimacy is so important when there are so many ways that everyday problems can interfere.
