I am committed to a girl since 3 years and now i don't feel sexually attracted towards her because now i consider the body shape more and according to me she doesn't have a good body shape. As i think more of my different behaviour i think porn is which i blame because in porn we see sexy ladies and fantasies about them and now in my life i also want the girl who have thick booty and big boobs similar to the girls in porn and this thing affects my relationship alot. All think about is that i can not leave the person i love because of this reason that "I WANT TO HAVE SEX WITH THE GIRL WHO HAVE GREAT BODY". After all this i came to know about this platform and i started following nofap and today after 21 days of nofap i can not stop my urge of watching porn and masturbation and i am very upset about my relapse and i want to try for 90 days but i am not sure that after 90 days will this improve my sexual behaviour if there is any expert reading this please help me!!
