Masturbation vs. My Sexual History

I found that I am afraid of having sex because of my not being able to perform. The last 2 girls I have dated wondered what the hell was wrong with me. In fact, the last one caught me looking at porn.
As I was growing up I started masturbating in high school. I fantasized about women, and did have some experience with sex, but there is really so much I don't know. What is sad is that I am 49 years old.
I too masturbate to porn on my computer, and have for the last few years. Its not a frequent thing. I can go days or a couple of weeks not doing it, but then something will trigger my urge, and I start surfing.

Practice makes perfect.

Yes, and I need a good educational sex manual.

Maybe you can find something on youtube. :]
