A few days ago I gave unprotected fellatio to a man of unknown status. This occurred at about 3 a.m. Fast forward exactly 36 hours and I had a white pus filled pimple (I think) and a couple of bumps under my lip that looked like they could possibly been razor/friction burn. I've read before that the onset of herpes is usually 2-12 days with 3-6 days being the average. If I had contracted herpes, would 36 hours be too soon to have full blown blisters? Would I have to have prodome and skin reddening before the blisters would show up?
