How can a teenage male lower his sexual urges?

actually, u can lower it but I'll give u these tips;

firstly, if u're in a relationship of some sort with a girl, cut it out.

try as much not to be alone with a girl. i mean alone

keep busy all the time. i.e make sure u're not idle.

if u believe in God, pray.

then if all these does not work. for sure you have to see a PSYCHOLOGIST
