Perverted Thoughts

Man...you're complaining this as an effect of 'bored' and 'having nothing to be done' whil you're still 16? Wow...you're pathetic.

16 heh? So it means you're still a first-year student, if I don't mistaken. Shouldn't first years be the most pleasant times in high school? That means you should have a huge load of things to be done. Try taking up things you like that takes concentration and dedication in it. Interact alot with others; this MAY keep your mind off those pervert thoughts...as long you don't hang out with slutty girls.

Discarding ALL porn stuff might be a good idea, as long as you aren't trying to get a new one. Try to think positive things, and try to avoid nasty thoughts. You may even try yoga or meditation; these helps improve your positive aura. But what I've mentioned above and all other advices posted here (yes, all!) won't even work if you don't have the true intention to stop. Just ask yourself, do you really wish to stop all those nasty stuff? If you do, and only if you want to so badly, then take extreme actions.

Above all, it's all in your hands.

Jam it back in, in the dark.
