Purple line up buttcrack but I’m male and 13 virgin

I noticed a line running up my butt crack with some redness sorrounding it it is itchy and not painful but noticeable. I have not had sex so I don’t think it’s any std I sweat a lot so could that cause the line

Fungal infection. Can be nasty. Use a coal tar shampoo or nizorol shampoo. Or antifungal cream.
I was daily with coal tar shampoo down that way.
