I've been chasing the same girl for three months, and I've got rejected. We had nothing to talk about left after that while. So she got bored of me. The problem is that I have no experience of romance. I am 20 and I haven't been in a relationship before and haven't kissed or had sex with anybody without paying for it. I have no slightest clue about how to start such a thing, and I need advice. What have I been doing wrong? What should I do?
