I'm a male high school freshman, today, something shocking happened when I woke up. I'm sure I didn't pee myself. I'm not like a bed wetter or anything. But my underwear and sheets are stained with this...sticky and slippery liquid kinda thing. Is this what people mean when they say cOm? did I have a wet dream? I can't remember what I dreamed about last night but I think a girl from my school was in the dream. But I don't think it got weird or anything like that... actually, It was kind of scary dream I often have... If this is a wet dream.. does that mean i'm a man now
