What the hell is this!?!

..so I only recall having a cold sore ONCE in my life.

I have been seeing someone for the last 4 months. We have spoken about the redness at the top of his dick (he tells me its because he is circumcised it is senstitive and gets sore) I have encouraged him many times to visit the GP and get a cream or something but he is always 'busy'...

I still give him sloppy BJs because thats my man and I love him! But have noticed in the last month or so....the skin around my mouth is very red, sore and sensitive. The skin becomes so dry it starts to crack and I just dont know if its a cold sore....or from his dick!

I will be visiting the GP soon, but just wanted to know if anyone has experienced something similar?

I feel as though the combination of spit and cold weather has got me here

..but slightly worried.
