So... I have a cold sore. I had one a couple of weeks ago too, on both occasions they appeared a few days after giving my dh oral sex. Having just had a baby, we'd had a break of a couple of months of any sexual contact and we have had no problems with any sti issues in the past (although I have had normal cold sores before many years ago).
Basically my mind is going into overdrive convinced that he's had sex with someone else in the past couple of months, got genital herpes without symptoms and has now passed it on to me. I know they are different types of herpes but I understand that it is possible for oral sex with someone with genital herpes can give you cold sores?
The fact it had happened twice - not sure if this makes it more or less likely? Can you get a cold sore from herpes exposure if you already have dormant herpes anyway?
Any advice greatly appreciated, no other reasons for me to suspect dh having an affair other than usual post-baby and hormonal insecurity!
