The diagnosis is as would be predicted - you are controlling your porn urges not specifically, but by shutting down whole volumes of your emotions. Your natural sex drive and your sincere friends are both calling you on the phone and you are not picking up.

What would typically happen in a case like this is that you'd eventually have a massive backslide/backlash and find yourself inexplicably way out of control on porn or cross-eyed with horny enthusiasm about a new YF something parallel. Don't be devastated with guilt if this happens. But if you're tough enough, you can keep this up indefinitely and live with the emotional consequences.

God knows how hard it is with your sexual orientation. His burden is light. You're only commanded to love as perfectly as grace allows with the aid of the Spirit, not to dam yourself off. (Yes, that's dam as in the Hoover Dam.) Maybe your not-so-Y F is a fine person whose heart is true and picking up for him might be worth the trouble of plunging back into your God-given limerent (http://en.wikipedia.org/wiki/Limerence) emotions again.
