You shouldn't let attention from guys determine your self-worth (although it certainly doesn't hurt
)
I think I look WAY better than I did in high school. Although I had boyfriends, I was a total tomboy/athelete. Since I graduated, I stopped playing organized sports and discovered my feminine side, lol.
Basically, if you carry yourself with conifdence, it will shine through and guys will be more attracted to you. If you carry yourself with the mindset that guys are not attracted to you, they won't be. No matter what, just be comfortable and confident in yourself.
