Help me to control my unwanted sexual urges

Hi, I am 20 yrs, old university student. I watched porn science 15 years of age..and also start masturbating....but thing got really worse when I became 18...

I start doing online sex chats using my PC and my mobile... I also had a GF at that time and I use to demands nudes...I even tried to force her to do that...but eventually that never happens. She left me...after some time I got new Gf...we use to talk romantically on Whatsapp but then... every time I get turn on I use to do the same thing...I even send her my dick pics...I don't know why but I feel orgasm by sending her nudes of mine...after some time she also left me because of my impulsive sexual behaviour ...

When she left me I went to a various online site to have sex chat..I spend lot of money on that... I send my dick pics to many of my female friends just to get the orgasm...when they ask me why I do that I just say that I mistakenly send those pic..and then I act to apologize...but then I realize that this way I will lose all my friendships and my relationships... I immediately stop that and try to stay away from online sex chat..but I am still unable to leave porn...

I still watch porn to satisfy myself..but I use to fap about every day..and now I feel dry and unproductive..please help me here...I use to be a talented artist and computer programmer..but I completely became a slave of my sexual behaviour...

plzz give me a solution to overcome my tired sexual desire...that's why I started NoFap
