Not engaged

I'm not engaged even if i'm almost 22 years old, I never had a girlfriend, I never kissed a girl (on the lips i mean), I never had sex and finally I never asked a girl out on a date. The strange thing about me is that even if I'm not gay, little or fragile (physically speaking). Absolutely no one in my whole life ever said to me that I'm ugly, but still this didn't helped me at all. Most of my friends are pretty much the same like me but still they are surprissed when they see that I don't react if a verry cute girl wants to flirt with me. All my life long I was a shy person and loved my parents but now even they are starting to wonder what could be wrong with me. The only thing they do not know is that once I said to a girl that I like her even if I had a bad feeling about being sincere with here and I was wright. Hope you understand my english and thank you for reading my post.
