heterosexual question

[Dave913]

I'm a male, had un-protected vaginal sex with a female 4 times in a 24 hour period. Her  HIV status is not known. She was on her period so there was bleeding , and blood was on my penis when we finished. I have no other STD's, no cuts or open sores on my penis. Am I risk? Let's say she is HIV Positive As a worse case scenario.

Having sex with a female during her mensuration period is an act of personal liking which has nothing to do with HIV if sex is either made with a person of known status or it is protected..

Since you had unprotected sex and were exposed to potantially infectious body fluids, get yourself tested after 3 months mark

[Frank303]

You did have a risk and to determine your status for this event you will need to test past 3 months.
The odds IF she was infected unless a IDU or CSW are lower and in your favour  Given the worst case scenario and she is positive, insertive vaginal sex on the period roughly doubles the risk of HIV reception than for sex when there are no menses. It depends on the viral shedding. If she has any STIs, candidiasis of NSU then there would be more viral shedding,
