You need to do more fucking! Instead of hiding away and thinking “My dick isn’t big enough yet, a little bigger and then I’ll start fucking”, you need to have sex with that girl at work and anyone else who’s interested! Once you start hearing positive comments from those women ( at your size, they’ll all have something good to say! ), your attitude towards yourself will start to change quickly.
In short, you need the positive feedback from REAL experiences, not delusional thoughts based caused by porn. Stop watching guys fuck chicks who are paid to be there - go out and get some for yourself!
