Nico,
I have that now. It is common. Most literature out there on porn addiction will discuss this as a symptom. The more work you put in, the more confidence you will build. I suggest finding a new hobby, especially one that pushes you out of your comfort zone and with risk, so that you might build your confidence in other ways. Don't worry too much about women for now. Once you help yourself and build your confidence, women will likely come naturally and at the right time. They will be drawn to your new confidence. In fact, you're here because you care about women and want to make a change. You're actually preparing yourself to be a good husband if that's something you're hoping for in the future.
