The Best Puberty website for boys is Kidshealth.org/Sexualhealth
if you're looking for safer stuff, try www.kidzworld.com. its a site designed specifically for teens and kids. also try facebook or myspace if you're an older teen (and if your parents'll let you!)
xnxx.com is a great one for what ever you are looking for...
Those sorts of websites don't exist, for good reason.
