Can you get hiv from drinking after someone , or say if you and the person were flirting an they clawed your back to the point you can see the scratches but they arent bleeding, and can you get it from someone biting your neck, or sticking thier tongue in your ear? my friend did that to me back in jan. she's had sex with many people, i have not had sex and ive only had one person i did oral with which was my boyfriend at the time.
