Hi, I had sexual contact with a man 3 weeks ago and i am very worried about whether i would contract serious std such as hiv virus through the contact. I hope you can give me some help on this. There was no penetration or fingering, only mutual maturbation, but at some point he touched his penis head with pre-cum, and afterwards touched my clitoris and near the vagina opening, and i was very wet. I am not sure whether those pre-cum had dried out or not when he did that... Do you think I am at risk? thanks you very much.
