Want more excitement? There are several drug-free ways to spice up your sex life. Having a date night with your partner — to remind yourself of all the reasons you adore each other and to relax by being wined and dined — can be great ways to stimulate your libido, says Anita Sadaty, MDa holistic gynecologist in Roslyn, New York. Of course, there may be a medical reason why your sex life is flagging. Diabetes, thyroid issues, cancer, and cardiac problems can lower sexual desire. Nerve issues, endometriosisor other problems can cause sex to be painful for women. And certain medications — like some for blood pressure, depression, anxiety, and even birth control — may inhibit desire. Sometimes, having more and better sex simply requires clearing your schedule. Sadaty says.
