So you decided to have a go at one of your fantasies and actually have sex during your lady’s period. Next thing on your mind is probably the biggest question: is it safe?
Believe it or not, the answer is “yes”. As long as you don’t mind the mess, sex during menstruation is safe. Let me rectify that: about as safe as it can be expected. Blood is a medium in which certain infectious agents multiply, so you might want to consider that before starting. Also, the chance of getting HIV is probably sky-high with all that blood around. Better use a condom if you are not sure of yourself or your partner. Still, there is no medical reason why a mutually monogamous couple (which is also free of STDs) should not have sex during menses.
However if you want sex and are not scared of anything then you can just go ahead and do it. Yet it is a good idea for the worst of her period to be over is you want to make it fun. Putting a dark or red towel over the sheets is a good idea as well as it will help to protect them. It’s fine for you to do any position but it is highly recommended to limit blood flow, for the male to stay on top. The use of a menstrual cup or diaphragm will also help to keep some blood in for a bit.
The biggest risks brought by sex during menstruation are an increase in the risk of pelvic infections and HIV (because the opening of the cervix widens) and also a higher risk of pregnancy. Yep, you read that right: pregnancy. Just because your lady is having her period does not mean that you cannot get her pregnant. It’s rare, I’ll grant you that, but it did happen quite a few times. Have fun and stay safe.
