Hi, I have a rash on the underside of my scrotum and is on both testicles. It has started to spread to the inner thigh. I ve had it for a week and all I ve done is gold bond. I feel it has worsened. It is kind of leathery but it really itches. I ve done some research and it is either a fungal infection or STD. I am a virgin so it can t be an STD. It has to be fungal. I have heard to use hydrocortisone, lamsil (I don t know how to spell it), etc. I was wondering what the rash is, and if I can short-term use triamcinolone acetonide cream, USP .1%
