Missed kisses and opportunities

1 summer ago when I was 15, I had my first kiss. It was with a guy friend and neighbor and we hung out over the summer and kissed a couple times (nothing more though really) and after that summer we didn't talk that much and never made anything official. I don't regret my decision not to date him, but sometimes I wonder what if. Whenever I was around him or other guys in the past that I liked, I'd always get this sinking feeling though. I liked hanging out with them but I always had a feeling that we weren't meant to be/ something was going to go wrong. So I never dated them (except one guy in 7th grade but that's a whole other story). But now I'm 16, never been on a real date, and a little worried that I'm not going to get to date/ kiss guys for a long time. Will I ever meet a guy that I connect with and that I don't get this sinking feeling?
