ive been with my partner for 13 months and never had anything like this before? we had sex in which i tore a bit. the next day wen i was inspecting myself i found some blisters? i went to the GP and she said this was more of a sweat rash cuz the heat but im NOT convinced 
it resembles a herpes outbreak. i would get it swabbed asap
i have had a viral swab, waiting on results. I am taking anti viral pills now
update - swab results were positive 
did they type ? and one day js really quick for a new infection
did they tell you if its 1/2 ?
had a viral swab with the GP on the monday and they rang with the results wednesday evening! ive had to go to the sexual health clinic to have further swabs! the GP gave me no other info
no im awaiting further results from the clinic
