Thanks for the replies, they are all very appreciated. The burning and bumps continue, I went into an STI clinic today and at first she did't see anything and then she changed her mind and thought there was something suspicious. I think she deals with this a lot so I tend to trust her judgment. She swabbed, did a blood test and started me an acyclovir 400mg three times a day. Now I just need to wait and see.
I am still torn about the girlfriend, I am missing her a lot but I also had reservations before. This is at least giving me some time to try and sort it out, hopefully I don't lose her if I change my mind. Anyway, I really appreciate the time you took to help me out, especially when there isn't a tangible benefit to you. I'll put in an update when any news comes back.
