im 30 years old, about a month ago i had protected sex with a new partner. 2 weeks after i noticed one morning that my scrotum was bright red. i put anti-fungal cream on it it didnt go away so i went to the doctors office in town, she said it didnt look like an std and she gave me nystatin and triamcinolone acetonide cream a few days later it hadnt let up so i went to the health department to get checked. the doctor that looks at all the stds there said she didnt think it was and std. i havent got all my tests back yet but 2 doctors dont seem to think its an std, what could it be and how do i get rid of it
