Penis size will not determine pleasure of sexual encounter

I have never had sex, mostly because I am very self-conscious about the size of my penis — it’s very small, though I’m average height. I’ve thought of surgery but I’m frightened that things may go wrong. I know it shouldn’t matter but it does. What do you think?
First let’s explode the myth. It isn’t penis size that will determine the pleasure of a sexual encounter. It’s the physical interaction along with the caring, sharing and communication involved that add up to good sex.
