Totally unrelated but:
My gf's 17 yr old brother asked me to show him how to shave the other day. I did. It made me laugh inside, cause here I was, taught myself how to shave, and this bio male is coming to me asking for advice.
Just wait til that happens to you.
As for shaving...even if you only have peach fuzz, it's a good idea to shave it off. You can tell when you do shave, even if its only peach fuzz. Its completely a myth that if you shave hair, shaving it alone will make it come back faster and thicker. But at least you won't have that annoying, more feminine peach fuzz.
