Sweating crotch during night?

This is kind of embarrassing, that’s why this post is anonymous.

I wake up all night to pee and I noticed that my underwear is wet all around the pubic hair area (I am always shaved, so no hair to blame for the heat) Is not my vagina leaking or something because my underwear is dry in that area.

I have to mention that is winter and I sleep with a light blanket on me and fan on pointing to somewhere else (just for the noise to sleep better) sometimes I am so cold I can barely move but still sweating down there.

Am I the only one?
