You are completely normal in my opinion. Everything you wrote is alot of what most boys feel when they go through puberty. Sexual desire is not something anyone can "control" regardless of what this priest said.. It's the religion aspect of this that makes you feel that it's "wrong" and that is so much why I do not practice or believe in any religion. I'm so sick of hearing how religious authority figures try to "scare" others into feeling guilt for natural things like sex, and masturbation, or even sexual preference. You are craving what so many many other people desire....sexual affection from another human being. I say you should enjoy and embrace your sexuality as long as you are safe and educated as far as protecting yourself from std's and unwanted pregnancy. Never feel ashamed !
