Another Awkward question!?

ooook so here we go...I was "reliving my self" (if you wanna be an adult master_bating) and I donno if its normal for some one at the age of 18 to increase in "load" size but when I got up it looked kinda like a small dog pissed in a spot on my bed.....like it was a small puddle should I be worried or is it normal? ((and yes I do lay down dont judge me lol))
