gnarly rash that I don't mind having

[syka16]

I have this rash in my groin area. It’s red but sometimes turns white and flakey like athlete’s foot when dry. I’ve had it before in high school and I got a cream that took care of it. But it doesn’t itch and I don’t really mind it that much since I’ve had it for 5mths. Then I looked down at my gf and saw that she’s got it too but up near her butt crack. Am I obligated to do something about this?
