2 days ago I had an encounter with a girl , we started kissing and flirting and she rubbed my Pines by hand and an I fingered her ,and I tried to penetrate her vagina without protection ,but when I just entered the tip of my pines I felt coming so I pull it out and came outside and there were no vaginal fluid at all , so what are the risk that I could have caught hiv .thx in advance for answering
