Welcome to our Forum. I'll try to help. From the sounds of things there is a fair chance that you were exposed to a cold sore (HSV-1). Fortunately, most direct exposures to cold sores do not lead to infection. there are several reasons for this. First, even though you may have never had a cold sore yourself that you know of. you may have been infected long ago, in childhood and if so, you will not be susceptible to infection since infection with HSV-1 protects from further infection. Secondly, even if you do not have HSV-1, I would estimate your statistical risk for infection as being less than 1%. Unfortunately, at this time, there is little you can do but wait to find out.
If you did acquire genital herpes from this exposure, you should develop penile lesions within 14 days of the exposure at the site of exposure. If you do not develop lesions by 14 days, you do not need to worry. On the other hand, if you develop lesions of any sort on your penis, my advice would be for you to have the lesions tested with a PCR or culture test for herpes. There is no other testing which will be helpful in this situation.
I hope my comment is helpful. EWH
Just following up to report that it's been 14 days and still no symptoms, so it looks like you were right. Thanks for the reassurance and keep up the good work.
