i had sex with a girl of unknown status and the condom broke while having sex, i pulled out as soon as i felt the change in sensation and immediately went into the bathroom to wash my penis, i asked her of her hiv status and she said she is negative because she is a nurse. i do not know the exact time i spent inside her while the condom was broken but am sure it was not more than 2 minutes as i pulled out due to the change in sensation. what are my chances if she was hiv positive?......please help me am scared
