"I am totally new to praying and all I've ever experienced during prayer is 15 seconds of relaxation."

Actually, given your age, and high (METAL!!!) testosterone levels, prayer is not going to be any more effective than masturbation in calming your agitation for more than "15 seconds." But don't despair! It's a matter of building up a habit of regular prayer.

I read somewhere that youth pastors are supposed to spend THREE HOURS A DAY in prayer, because they need to deal not only with their own agitation, but with the screaming, ungrounded energies of lots of kids.

When you're young, it's kinda hard to tell the difference between the empty fantasies of jacking off to an image, and the quiet, talking to God you do in prayer.

I mean, in either case, there's nobody there, right? So what's the difference?

So you have to look at the "fruit." Somehow, masturbation leaves you emotionally emptier, where prayer leaves you emotionally fuller. TIS A MYSTERY, MY BOY!!!! (Lol god.)
