[Question #4373] Transmission of HSV 1 Oral Sex

29 months ago
Hi, I’m a Hispanic female 25 years old and I have had oral cold sores haven’t had one since I was 14. On September 15 I realized I had a small rough spot on my lips that was near the corner and it had a very small almost unnoticeable spilt in the middle it went a way in like 3 days with lip blam. Now on Friday Oct 5th a very small bump appeared near where spot once was no fluid or blister. I started to freak out cause my girlfriend booked us a room to be intimate for the first time. I put on lip blam and abreva on and by the next day afternoon it was gone no bump no redness. My friends told me that I was freaking out and that it wasn’t a cold sore cause it wouldn’t leave that quick. I had oral sex with my girlfriend twice on Sunday and Monday  no protection,I know it was stupid but I honestly thought it was nothing. Now I’m worried that it was a cold sore because the rough spot came back only bigger and with tiny pin like bumps no blisters and when I run my tongue over it seems to be sore or cut up, went to the doctor they thought I was being dramatic and that it was dryness but only on that spot? How likely was it that the bump was an actual cold sore? can it leave that quick? If it was did I give my girlfriend genital herpes 1? She said that had a blister when she was little and had a fever but it went away like in a day, is that a cold sore and does it prevent her form get it somewhere else? Is what I have now on my lips a cold sore or just a dry patch? Thank you!

The only way to know if the thing on your lip is a cold sore or not it is to have it swab tested, preferably the PCR which is more sensitive than traditional culture. 
So your partner said she had a blister when she was little  - was that on her lip?   Also herpes lesions don't normally go away in a single day - or even three days - which makes me less likely to think that the think on your lip was herpes. 
Here's the other thing - has she had any symptoms?  This was a month ago and if she was going to have symptoms with a new infection, she would have had them within 2-10 of the contact you had with her. 
If you both have HSV 1, then you are both very unlikely to get this in a new location on your body (such as genitals).
