I'm a male, and 2 days ago, my girlfriend of several months spent the night at my place and we had sex, that night and the next morning [which would be yesterday], and I performed oral sex yesterday morning. I have hsv1 and she is aware of it, and we have engaged in such activity before. I noticed it the first time 3 years ago, got a recurrence a year later, and have been latent for 2 years. Since then, I've had partners who couldn't remember having a cold sore in the past who were also aware, and had performed oral on them frequently for months without incident.
After she left, maybe a couple hours later, I noticed my lip felt a little swollen, I looked in the mirror and didn't note anything like abrasions or blisters. I thought I might have bit it, or perhaps it was bit during kissing. I went out for the day and when I came back perhaps 7 hours later, I noticed yellow flat crater-shaped ulcers on my lower lip, where I had felt the swelling occur. I hoped it was a bite mark or canker sore as it was just inside where my lips meet, and i had not experienced any red clusters of blisters. Only the initial swelling sensation followed by ulcers hours later [which I thought took at least a few days and after forming blisters.] This morning it seemed to be crusting over as I would expect a cold sore to do, and I'm feeling a mild throb. So, I'm thinking this is a recurrent outbreak though it seems to have skipped the typical blister stage. Perhaps, it's not?
My concern is that if it is an outbreak, which I'd guess it is, and i was in prodrome and I hadn't noticed yet when i performed oral sex on my girlfriend, which was foreplay and was probably for a few mins. She said she couldn't recall ever having a cold sore. I'm worried about transmitting and hoping everything will work out for the best. How concerned should I be? I'm fairly worried because when I contracted this my ex was getting her first outbreak and didn't know she had it or at least didn't recognize the symptoms. I'm hoping that because this is a recurrence the shedding will not be as intense as my ex's. Is there any information of the risk for prodrome or only a few hours before prodromal phase? If it was early prodrome, could she still not contact it just based on chance or a percentage? I read one forum with a similar scenario and it appeared there was no transmission and that perhaps the prodrome started after the oral sex due to minor trauma. I hope we are that lucky and really hope she wasn't exposed to my hsv1. I can't imagine how bad I'd feel
