According to a 2002 study from Yale School of Medicine, sexual activity, orgasm and tampon use during menstruation seems to help lessen the risk of developing endometriosis. However, rumor has it there are couples who enjoy sex during a woman's period for other reasons as well. Here are some tips that you might find helpful.

Oral Sex during Menstruation

Some couples are fine with oral sex while the woman is menstruating; others wait a few days until the menstrual flow has stopped. Here are four possibilities if you don't want the mess but don't want to wait:

Sexually Transmitted Infections: While plenty of people are willing to speculate, little if anything is known about the true risks of doing oral sex on a woman who is menstruating. A conservative approach is in order if you are not in a long term monogamous relationship or if the woman has any sexually transmitted infections. You should never do unprotected oral sex on a partner if you have a chancre sore or active oral herpes in your mouth, or if your partner has a herpes outbreak on his or her genitals.

Intercourse During Menstruation

Some people fear having intercourse during a woman's menstrual cycle. But menstruation causes absolutely no harm to either partner. In fact, the contractions of orgasm seem to push accumulated fluids out of the uterus which may help decrease menstrual cramping.

Intercourse with a menstruating woman sometimes feels extra-nice for the following reasons: 1. The vagina might be super-lubricated due to menstrual secretions. 2. The added menstrual swelling might help a woman have a really intense orgasm. 3. Some women get extra-horny during their periods; this might have to do with a change in hormones, or perhaps they feel more relaxed since it's harder to get pregnant, although pregnancy is still a risk.

As for the aesthetics of midperiod intercourse, sheets with menstrual lovemaking on them usually wash clean, but so what if they don't? Guys shed that much blood during a hard-fought game of football and consider it a sign of courage.

Regarding Sexually Transmitted Infections (STIs): You will find lots of warnings about increased chances of getting STIs when having intercourse with a woman who is menstruating. However, there aren't exactly gobs of studies that show this to be the case. So unless your health care professional advises otherwise, the same rules should apply for sex during a period as when having sex at any other time--if you aren't in a long term monogamous relationship or if your partner may have an STI, use a condom or other barrier types of protection at all times whether a woman is menstruating or not.

On all matters of a medical nature, please consult with your healthcare provider about your particular situation.
