Hi Doctor, Recently I had sex with prostitute who was on period. But I had condom on, I keep my penis was inside her about 5 min, I took it back when she sad she is having pain. I did with hand with help of her. After I released sperm, I observed top of the condom having her blood. While I removing condom her blood was spread on my penis on front (Actually this is first time I went to prostitute, so when I saw blood I was nervous that it came from my penis and started removed fast). Condom is not burst only blood was spread on my penis I bit worried will I get STDs or HIV with this case? After how months I can do HIV test?
