Does sex during periods cause HIV infection?
Sex during periods cannot cause HIV infection unless one of the partners is HIV infected. Unprotected intercourse with an HIV infected partner can cause HIV infection, regardless of periods. The only connection between HIV and sex during periods is that the chances of HIV transmission from an HIV infected person to his/ her partner are higher if they have sex during periods. If you have the slightest concern about HIV infection, the thumb rule is to use a condom regardless of periods.
