Getting into a relationship?

I'm 15. All my friends and the people I know are telling me I should get a girl friend. I want one but I don't think I'm capable of shallow 2 week back and forth recitals of meaningless "I love you(s)", let alone a real relationship.I live with my father. The majority of my adolescence has been spent with my father. I don't know how to act around or open up to girls. I'm ugly/unattractive/average whatever you want to call it. Before you say looks aren't everything, think about how much "everything" is. The only time girls talk to me is when they are trying to give me a psychological vasectomy. Ironically, my friends moms and their moms think I'm gods gift to man. How can I let my guard down and keep it down? And do I really want to do that?
