im getting paranoid if i have some sort of infection, can you help?

So I've been noticing a rash in my scrotum on the right side. At times it may itch but nothing too crazy. I notice if i scratch it it gets really red and irritated. In one spot it almost looks like an open cut as if i broke the skin when i scratched down there. I've looked up herpes symptoms showing multiple bumps with clear heads that burst then scab over and I have not seen that. I religiously use condoms so im getting anxious what is going on. I saw a dermatologist a week ago and she said it didn't look like herpes but we would have a follow up soon. Any idea what this could be? it's like a small rash it's really sensitive and irritated then goes away after a few days. I'm stumped. I've NEVER had unprotected sex, and with my luck i rarely get sex as it is. I'm hoping it isn't anything related in that area but im not sure what else could be going on.
