Masturbation is entirely normal for a boy of your age. But from the sounds of it you’re probably overdoing it. Trouble is - when you watch a lot of porn - you get hooked on it. So first thing is to ditch the porn- or if you can’t stop altogether then set yourself a limit of say 2 or 3 times a week. Then try and stop altogether.
I don’t know what you mean by “you do sexual harassment!' Are you speaking to girls on the phone, or meeting them, or what?
I looked up sexual harassment and it says it could mean a lot of things. Some of them are
- Unwanted pressure for sexual favors
- Unwanted touching, leaning over, cornering, or pinching
- Unwanted sexual looks or gestures
- Unwanted letters, phone calls or materials of a sexual nature
I really hope you’re not into any of these things because if you are then you have a problem because it will only lead to trouble. Big trouble.
You say you haven’t got a girlfriend - but believe me that won’t happen if you carry on doing ‘sexual harassment‘

Get out more with your friends, do some sport, get busy, get a part-time job. If you stop thinking about yourself and start thinking about other people you will become the kind of boy girls want to date.
