I have a issue my penis goes up and down alot thruout the day is it normal

If you're between twelve and thirty or so, random - and often embarrassing - erections are completely normal.

There's really not much you can do to stop them, since the bit of your brain that controls erections is not under your conscious control, and all sorts of random things can trigger a boner.

About all you can do is try to minimise the embarrassment they cause. You could try wearing loose-fitting outer clothing over underwear that's snug enough to hold your penis in place so it doesn't get any random friction, and position your penis so it points upward. That way, when you get a stiffy, it won't jut straight out in front of you.

Why is this under spitituality?
