According to”Healthline”
The vastest downside to having intercourse during your period is the mess. Blood can get on you, your partner, and the sheets, particularly if you have a heavy flow. Aside from dirtying the bed, bleeding can make you feel self-conscious. Anxiety over making a mess can take some or all of the fun out of intercourse.
Another concern about having intercourse during your period is the risk of passing on a sexually transmitted infection (STI) like HIV or hepatitis. These viruses live in blood, and they can spread through connection with infected menstrual blood. Using condoms every time you have intercourse can reduce your risk of spreading STI.
If you plan to have intercourse during your period and you’re putting on a tampon, you need to remove it beforehand. A forgotten tampon can get pushed so far up into your vagina during intercourse that you’ll need to see a doctor to have it removed.
