Absolutely the same happened to me.

 It's incredible how similar my own experiences were, and how difficult it was for me to go through the horrible humiliation of not understanding why my penis wouldn't react to these incredibly hot girls. I got a reputation among my friends for not banging my girlfriends, and more than once I dumped a girl after a week or two because I was afraid of becoming any more physical.

 It took a few weeks of abstinence and trying with my hands before I got myself off. I remember exactly the date and place of my first manual masturbation, it was Summer 2005 - it took a long time but yeah, it meant I was free!

 It was less than a year later that I had another girlfriend, and it took some courage after so much humiliating failure, but everything worked well after 6 months of 'proper' method.

 But you know - it really ruined my life for a long time. So many girls I cared about I let go, or humiliated myself in front of. My life would be very different had I not spent the first 23 years of my life fucking my mattress. There's a chance someone out there is reading this who gets off in this way and will have, or is having, an experience similar to mine. All I can say is - stop, wait a bit, try the 'digital' method, or your love-life is screwed.
