Hey so this is a little awkward but I have a question. I'm 15 and my penis is normally 6.5-7 inches (which is actually kinda large for my age) and I wanted to know if it's normal for size and thickness to go down occasionally because for some reason when I became erect and masturbated for the second time (really stressful few days) it looked different in size and shape.
