Labido : You sex drive comes from not only hormonal fluctuations in your androgens (testerone being the main one), but also varies based on your level of rest, level of stress and your interpersonal reactions with your partner. As women age they do sometimes have a drop in androgens though and a decreased sex drive. Weight changes also affect androgen levels.

It doesnt mean: It doesnt mean there is something wrong. Libido is linked to man different things. It could be up or down based on your stress levels, your emotions, what medications you take, how much sleep you get etc. Many different factors play a role in your libido. If you find it significantly concerning see your physician as your levels of testosterone also play a role.
