I think I had my first wet dream?

Hi, I think I had my first wet dream last night..

I was dreaming that I got a head by my doctor, and in the dream I cummed, and when I woke up I had my largest erection and I there was a wet spot on my underwear. I've never ejaculated before.. I'm just about 15 btw

Was this a wet dream? Or did I really have to pee..
