Why do girls dont like guys who masturbate??

You're 15, that's why. Girls your age find it revolting.

 

It's because you are wasting your sexual energy. You are throwing it into the trash instead of sharing it with your girlfriend or doing other amazing stuff, may be just go out and try to be a better person. Girls will also feel unwanted, not pretty enough, as the message you are sending to them is basically "Go away. You are too complicated for me, let me just sit in front of my PC alone and get off on my own." In this case, she will have every right to leave you. It is great that you started controlling your fapping behavior, but apparently that relapse was one relapse too much... nevertheless you should use this as a motivation to cut PMO out of your life completely. If you take this one leap you will not have that problem ever again.

 

It happens bro, just don't fap. You'll get other girls cuz youre young. Get busy bro, I suggest lifting weights and playing sports and read to keep busy. It will do you wonders.
