find some one to talk to ....take a walk ....go to a movie....do home work...
find a nerd or dweeb and learn some thing....
temptations only succeed if you are alone, lonely, offended....and yield...to what you are tempted with...sin
make a list of why not to do what you are wrestling with...
heath..std....marriage...pregnancy...exposure...humiliation...bondage.......all sin is short term relief to a long term problem...(hell)...where none of us want to go ....
the fact that you post, ask means your heart is right, you just need a few prayers and an accountability partner...
