>>33374292 (OP)You fried your brain with porn and indulging absurd fantasy that'll never happen. You need to give it time to heal. The longer you stop watching porn and indulging this incest thought, the more your behavior will normalize.
Look, bro... The first couple times I had sex I had trouble performing and thought I was impotent too. You're not. Sex with a new girl is a lot of pressure, it's not quite clear how you're supposed to please a particular woman, you have to take the lead, and stoke her up before giving her what she wants. It's kind of normal for your first couple experiences to be disappointing.
My problem was jorking it too much and taking adderall and smoking cigarettes, vasoconstriction is the enemy of an erection. I just happened to be too busy to jerk off for a few days before running into an old friend from school and landing a date late that night. I was so horned-up in the back of my mind that all of a sudden these sexual behaviors which were scary to me operating on auto-pilot. I was direct, decisive, took her back to my dorm room and busted a rope all the way up to her tits.
Just give it time, quit jerking off, and go into a date horny.
