Just as you may find that your mood fluctuates throughout your menstrual cycle, you may be one of the many women who notices that their sex drives (or “libido”) shift over the course of their cycles. The reasons for increased libido are complex, and most likely involve an interplay of hormonal shifts, emotional states, and thoughts. For instance, some women report that they feel more sexual when they are on their period because they feel that the likelihood of a pregnancy resulting from intercourse is decreased (though remember, getting pregnant is still possible, even when you are on your period!) Other women feel more emotional during their period, and find that sexual activity is a natural outlet for this energy. Still others find that having an orgasm helps relieve their period-related cramps and body aches!If you are sexually active while you have your period, just remember to take all the precautions against pregnancy and sexually transmitted diseases that would you would at any other time of the month. Choosing to have sex while you are on your period is a matter of personal preference – and as long as you and your partner are comfortable with your choice and practice safe sex practices, you can enjoy sexual intimacy at any time of the month.
