hmm..after a couple years of inactiveness i can't help but answer this:
the testes hanging this is completely normal...as u already pointed out to urself....
the no wet dreams thing is probably cuz u masturbate often...i've never had one either personally...and i'm also 15
those spots...i dunno what they are...but i have them too and i'm CERTAIN they're normal
i'm pretty sure the spots on the lower part of ur penis are hair follicles...well im not sure thats what u call em..but it's where hair grows out of, every1 has them
absolutely no point to the vein squiggly question...every1's different and every1 has veins..
that masturbation/urination question...i get that too, there's this thing in the prostate which stops u urinating wen u have an erection...i'm pretty sure it's just that canal switching back to normal..
and to that masturbation question...it's ur choice, whatever floats ur boat
neway, u can stop fretting over little details now, every1's different
nice name embarrassment
P.S. Poms knocked u outta the final, kiwi's suck
