I had a descreet sex with a woman I met on that same day, but she touched my penis and scrached the head of my penis and it was bleeding. I was using condom, but even the condom was full of blood. But just my blood, not hers. She did not bleed, neither did she have my blood in her vagina. Do you think there is a risk of me getting an STD or HIV?? I am very worried. I have a smalll wound, and it is causing me pains when I urinate because it is right on that hole of the penis. I need your help. Tell me please, and what should I do now??

Even without a cut there is a danger of transmission of many STD including HIV. A much higher danger of many of the others. While a condom helps greatly, it is not 100 percent effective in all cases.

If you were bleeding so bad you filled a condom with blood, what were you thinking ?

See a doctor and get regular tests for STD's
