Hey doc. So yesterday I was here at home with my girlfriend and things got a bit physical. We were touching each other around and one thing led to another and I then rubbed my penis around her vagina. I had not ejaculated that day at all and there was no clear sperm at the tip of my penis. My penis was pretty dry and my skin partially covered the tip but I'm still extremely scared. I did NOT penetrate her at all but I did rub around. I'm very concerned about the whole per-cum subject and I really need some good news right now. I will never try anything stupid like that ever again. I need knowledge from a professional. Please help me! :'(
