First off, I'm an active 21 year old male. I gym around 3 times a week lifting, and otherwise I work in hospitality. I have had these strange red marks on either side of my crotch, around 2-3 inches away from my genitals. Thinking it is a sweat rash considering my activity levels I have applied 1% Hydro-cortisone cream to the area for a week with no results.

This is on the left side, they almost appear to be in a line.
I have had this for around 4 months now. They don't itch. There is no weeping, they are just red and slightly raised. Nothing on my actual genitals.
