crotch on fire in the shower

[diamondcat]

I get that sometimes, if it's hot out and I've gone for a long ride. What seems to set it off is if I pee during the ride, that seems to irritate the delicate tissues more than normal. I may not feel it until I get in the shower, though. I do use chamois cream, but it doesn't always stop this.
My saddle is fine and I wear 2 different brands of shorts that I love. I just don't let the water hit me near those parts when this happens and definitely no soap near there, ever.
Tea Tree oil helps sooth this.

wait, so you dont wash your crotch after rides????!
