I am a teen boy (13-14) and I am wasting 15-20 minutes almost every day to watch porn and masturbate on it.

Is this normal and does it do any harm on me?

The American Academy of Pediatrics calls masturbation “a regular part of normal adolescence” (bit.ly/AAPSexHealth), so no worries there. Porn use, while also extremely common, may cause problems. Be sure you recognize that porn is not reality and don’t build your fantasies and expectations of future sexual partners on it.
