Olive,
You are at an age where your body has developed a lot of curves, which catch a lot of boys' eyes. It feels good to pick up on a person's attraction to you.
In the mid-teenage years, we seem to become more and more aware of how boys and men are willing to do all sorts of things in order to be allowed to view, feel etc. A lot of times, somewhere along the way, girls forget to ask themselves how they feel. That's a really important aspect! While part of you may really enjoy the attention, and even crave it (to some extent), you need to ask yourself how you feel about *James having some control over you physically.
Personally, I would advise you to be a little more careful in the way that you dress and your actions, so they aren't misinterpreted as come-on's by guys.
