<human>: Can you condense the text into a few key points?

Hey guys thanks for taking the time to read this. I am a senior in high school who has never had a girlfriend. But I'm clueless and don't get it. I can make girls laugh easy and it seems like collectively they like me. I'm athletic and intelligent now I'm not the most beautiful guy but I'd rate myself on the high side of average and I'm strong. But girls don't go out of their way to flirt with me like I see them do with other guys and won't flirt with me in the same way when I approach them. Also every time I've pursued someone I get lead on. (This doesn't hurt my confidence and is potentially completely my fault ). I play sports, I'm social, and I have friends. What do I do wrong? How can I improve this aspect of my life?
