Sex during Menstruation – The Good, the Bad and the Ugly

Sounds gross, yes, but there are some who practice it.

I’ve come across people who ask how safe sex is during menstruation. It is still a controversial issue. For one thing we are sure about is that it never fails to make you frown upon hearing it.

The good and bad of period sex are yet to be discovered. However, a number of theories suggest that the practice more of a disadvantage rather than an advantage.

The Good

In a way, it relieves menstrual cramps. How? Endorphins (a type of hormones to relieve pain and affect emotions) are secreted during orgasm and thus decrease menstrual pains.

The Bad

Naturally during menstruation, the veins of the uterus are congested and are prone to rupture easily. Vaginal walls swell as well during menstruation. This explains the dull pain in the vagina during menses and is 100% normal. Having intercourse during your period can increase the chances of irritation to the swelled up walls. The advantages of endorphins at this point mask the danger of period sex where irritation of the vaginal walls and introduction to infection are major risks. Any wound or bleeding is a fine gateway to infection.

The cervix is slightly opened during menstruation to let out blood. This heightens the risk of infection, not being limited only to the vagina, but additionally to the uterus. The penetration of the penis into the vagina during menstruation is no more than the introduction to germs at a time when the body is unable to fight them (studies have shown that immunity is decreased during menstruation).

Orgasm results in rhythmic uterine contraction. During menstruation, this helps shed blood faster and shorten your periods. A similar reaction happens when a menstruating woman lifts up heavy loads or does strenuous exercises. This explains why most athletes experience amenorrhoea (missed periods).

Sex during the menses also increases risk of HIV infection.

The Ugly

Obviously, period sex can be really, really messy and unhygienic. This fact by itself drops the interest of both parties about the idea of having sex during menstruation.

So, is period sex good or bad? Well, momentary pleasure versus risky health – you be the judge.

  1. My boyfriend and I have period sex all the time as my hormonal implant causes near constant light bleeding, however last time I was slightly heavier during and he was experiencing discomfort, we stopped before he came, and noticed blood and fluid had made its way into his urethra. Would this have caused his discomfort?

    • Dr Elaine Loh

      There are a lot of factors that can cause discomfort during sex. It is impossible to answer your question. However, blood and fluid should not really cause discomfort. In fact, it gives more lubrication.

  2. Hey Doc me and my boyfriend had sex while I was on my period and my monthly stayed on 8 days… What does that usually mean?

    • Dr Elaine Loh

      I don’t really understand your question. If your concern is about pregnancy, I think your risk of getting pregnant is negligible if you have sexual intercourse during your period.

  3. hi doc.last night i had sex with my gf who is having her period already, i used a condom during the intercourse ,but found blood stains around d condom and also on the sheets. is she really safe and likewise ,am i also open to get infected

    • Dr Elaine Loh

      If she was having her period during intercourse, I am not surprised that you found blood stains on the condom and bed sheet.
      If you are referring to STD, I think risks of STD transmission is low given that you have used a condom. If you are concerned, please see a doctor.

  4. I have sex wit my boyfriend the second day of my menstration,and the blood stop to flow the third day, any pills that can be taken pls doc, nd wat is the chance of my pregnancy, because he did withdrawal.No condom

    • Dr Elaine Loh

      Your risk of getting pregnant is extremely low given that you had sex during menstruation. However, if you are concerned, please visit a doctor for an assessment and emergency pills.

  5. can i sex with my file, she is yesterday is period start ,

    • Dr Elaine Loh

      I don’t understand your question. Last time I checked, a file is an item. I’m not sure how you concluded that it’s a she.

  6. Zamoorat

    I have done sex with my husband and after 3 to 4 hours my periods start at the exact date is it harmful for me or not ? Also 2 to 3 time my liquid out during periods without sex is there any disadvantages of it?

    • Dr Elaine Loh

      Of course it is not harmful. It is not even harmful to have sex during period.

  7. hi doc. i just had a sex with my boyfriend last night without protection but only withdrawal and as i saw on my underwear after the sex, I saw some spots so im thinking that i already had spotting before we do the sex and this morning i have my period . Does me and my boyfriend safe? or are their any infection might happen to both of us? what will we do in order for us to prevent?

    • Dr Elaine Loh

      Safe from pregnancy? Yes, if you had menstrual period the next day.
      If you are concerned about STD/infection, see a doctor to get an assessment done.
