Haha, did something very similar today. Some hot chick called me today and she quickly directed the conversation into sex, turned me on so much I had to rub one out on the phone. I was only on day 12 of no fap but other than today I have had no urge to fap at all. As the good doctor says the real key is avoiding internet porn, and I haven't so much as peeked at that for an instant since I made my decision (albeit only 12 days ago). The very thought of fucking myself up worse by watching any porn and having PIED ever again is so hateful to me, watching porn is like suicide.
What I did today is not something I want to do anymore though, I will go on the hardest hard mode possible to speed up my recovery ASAP.
