Hello. I’m an 18 year old male. I regularly have unprotected sex with my girlfriend, who I’ve been with for 3 years. About 2 weeks ago my scrotum developed a burning/tingling sensation, particularly when sitting down and was really red and dry. I immediately went to my local GP, got screened for STI’s all coming back negative. Since then the burning has continued around and below my scrotum. I applied anti inflammatory for a few days which did nothing and I am now using anti fungal cream, canesten. It doesn’t seem like either of these are working. I am stressed out and am not sure what to do.
