She can't finish me off.

Hey, as in topic name, I have a problem with feeling sensual emotions, when she strokes me off, or blows me. Same with vagina. I know it's because of my masturbation addiction, i've been doing it for 5 years. Why?

The problem starts in gymnasium, when i was 14 year old, and bullied. The amount of stress produced on for example sport lessons, where my class mates were hiting me with balls or the teachers, who didn't understand me and the problem. I started to be alone in this, started to eat to reduce stress, but this only got me fat and caused more problems and agressive stance against me. My grades were bad, my family rejected me, so i needed to find solution. And the solution for that was masturbation, that freed me from stress, so i could start thinking about myself, getting better grades, defending from bullies, it all brought me here. Now i am 19, i have friends, i am skinny, im in high marked computer science school, i got gf, that had the same problems, so when we meet in the web after years we become lovers. I rarely drive to her, but now we are in next step in our relationship - sleeping with each other, and well - making off.

I watched porn for 5 years, so i have big knowledge of sex, because porn wasn't my all crap that i needed to masturbate, the more years come, the more things i was learning, searching and so. So my partner have good times with me, but I kinda not. Because of 5 years of addiction i can get boner, but i can't orgasm without my hands. My thing don't feel mouth, or vagina, only her little hands a little.

I know i should stop watching porn or masturbate. But what can i say, my gf is very sad because of that state, and is there any thing, to help me? If not (that's obvious), how long should i regenerate, until the two sites can enjoy proper sex? The time is a big deal here, because the more time will go off, the less ideas i have to help my gf stay good and don't think about that stupid shit. Any ideas, how to tell her about all this problems?

Ps: Sorry for my english, if you catch any mistake i made, i am very sorry
