The best way I can explain it is like how the back of a Playstation or other console when it gets hot and the air coming out of it is hot. Combined with a slight armpit smell. As long as I have been on the internet, I keep reading about how women smell “fishy” down there, and I was always confused by that. Am I just weird?
Nope. You’re normal.
I’m no expert, but I’ve only experienced fishiness after sex or a few days without a shower.
