Porn and masturbation addiction, how to quit?

Hello.
I am 30 years old and i am addicted to pornography last 16 years, in the last 3-4 years i have started watching sissy hypno porn because i’ve always liked to occasionally anal masturbate with fingers even though i’m not gay, i’m straight and i love girls, but later, more precisely last year, i bought a dildo, woman stockings, chastity cage, nipple clamps and started doing it more often, orgasm from anal without penis stimulation was funtastic, i have never had such a strong orgasm but after every orgasm i felt guilty and low self-esteem and the feeling that i will never have a girlfriend again, in the end i threw everything away, now i masturbate normally with penis but i can't quit sissy porn because it excites me very much, i want to give up pornography and masturbation and just have sex with girls.
Pornography ruined my sex life because i had my first sex with a girl when i was 28,
for years i had low self-esteem because i was virgin, after the first sex i felt better but
but 7 months ago i met another girl, we had sex but after sex she asked me at what age i lost my virginity, i sad 28 but she got angry because of it, she told me that she would not be my sex teacher and that she had 10 years of sexual experience and she left me, after that i couldn't accept what she told me and i felt low self-esteem again,
after that i started watching sissy porn hypno again and i don't know how to quit.
HELP ME!

Sorry for bad english.

 

Thank you for your support
From today no more porn and masturbation, only real sex.

 

After 5 days NoFap i masturbated this morning, now i going again NoFap from today, it is very hard but now i will be stronger!

 

Yes, you're right, i lost my virginity in 28 and because of that i am afraid that every girl will expect more from me in sex, i only had sex with 2 girls in my life, that's why i had a bad experience with the last girl and she left me because of a my little sexual experience.

I watched some amateur porn but i know it's best for me not to watch ever again, that sissy shit is most addictive porn, because of porn i have fantasies of being submissive and fucked by a woman with a strapon and also i have cuckold fantasies, i just want to have a girl with normal sex life.
