Enlightened dads and older brothers always tell the younger guys, "Do it often, have fun, you can't do it too much, and USE LUBE! Else you'll get sore!" Makes it easier to concentrate on school work (my buddy and I always had a good wank before studying), helps your immune system, makes you a better lover in the future, and it's just the most pleasurable thing you can do that's free! Jerk on, gentlemen...
