Your sexual desire, or libido, is the feeling of wanting to engage in sexual activities such as masturbation, sexual thoughts, fantasies, or sexual contact with a partner. Everyone's libido is different and can be affected by medical conditions, hormone levels, medications, lifestyle and relationship problems. It can also change from one moment to the next. If your libido causes you distress, it is important to seek professional help.
There is no right or wrong level of libido and no such thing as “normal” when it comes to how often you have sex. However, there are some natural hormonal and health changes that can affect the libido. Past experiences, the availability of a willing sexual partner, physical and mental health, and the stage in which the relationship is in can all influence a person's libido. Some women feel less interested in sexual intercourse when they take contraceptives that contain hormones.
If you don't feel well after engaging in sexual activities, that can create a circle of negative feedback that prevents you from wanting to participate again.
