Most Helpful Guy
It's not easy for anybody when it comes to obtaining a boyfriend/girlfriend relationship. It sounds like you have gotten rejected already a few time or at the very least you haven't caught the interest of those who you are interested in.
You need to get to know the guys you are interested in and build a relationship even if its informal that's the first step to getting on their radar, once you are you may learn what they like and you can use that to get a bit closer to them. Appealing to what they like will them a bit more receptive to talking with you and getting to know you better. Thats a start there, there is no surefire way, but hopefully this helps you.
Good luck!1THIS IS NOT RELEVANT ANYMORE
