Dear doctor, I made out with a guy. I don't know him well and have no idea of his hiv status.
I refused to give him blow job, but he suddenly touched my lips with his penis head for like 1~2 seconds,and he may have secreted some precum.
There were no cuts or wounds on my lips, but I am wondering whether lips are normal skin or mucous membrane. If his precum touched my lips, would this possibly lead to hiv infection?
Dear doctors, please kindly address my concern, thank you very much.
