Hi there, my girlfriend and I were being romantic last night. We are both virgins although I masturbated three times before we proceeded with Fourplay. I had a minimal, but noticeable amount of post semen on the tip of my penis it and I touched her vigina for literally around 5 seconds. I didn't penetrate or anything. She wiped her vigina right after and went pee. Is there any chance of pregnancy? I'm am probably just paranoid
