Hey, a girl gave me a bj without a condom. I then noticed a possible cold sore hiding below her lipstick. She hid it really well. Chances of it being a cold sore is quite high. What should expect? What is the probability that I contracted Herpes?

Have you ever had a cold sore on your lip in the past, even as a child?  If yes, then you are already positive for HSV 1, the cause of cold sores.  If not, you may still be infected with HSV 1, half the population between 14 and 49 has HSV 1.  I would observe your penis carefully for about 10 days and if you develop any kind of break in the skin of the penis that isn't usual, please have it checked out right away.---

Thanks for your response. I never had a cold sore (as far as i can remember). If i don't get it checked out, will it then heal on its own? Or are there any meds that i will have to be put on? 

What do you mean, get it checked out?  You didn't say anything in your previous post about having genital symptoms.  If you have symptoms, please get them checked out and swab tested to be certain that it is herpes.  You don't need meds for it to heal, it will heal on its own if it is herpes, but you should be evaluated.---

Well so far no symptoms .. i meant , assuming i get lesions, why do i have to get em checked out when im sure its herpes .. why the formal diagnosis. Thankfully, so far im good .. i hope itll stay like that. Thanks
