I went to a stripper's (frequently has sex for money) apartment last week, and I had sex. During sex, I noticed some blood on the condom when I briefly withdrew. She finally told me she was on her period. We continued anyway. I finished and removed the condom by stretching the base of the condom on the left and right ends so I wouldn't roll it down. I carefully pushed the condom off without touching the head. I wiped away a little blood where the base of the condom was with toilet paper.
We started again with a new condom, but the blood continued to flow. By then, I had a rag to carefully wipe away the blood before it touched the base of the condom. I noticed the condom rolled up a little, so I rolled it back half an inch. It made me a little uncomfortable, and I went flaccid for a minute then I was erect afterward. I couldn't finish so I removed the second condom the same way I did the first one.
Based on this experience, do I need a HIV test? Am I in danger of any STD/STI? When should I get tested?
