Hey, you're in the exact situation as me, same age and everything but I'm not looking for anyone right now.
Basically, the best thing to do is just enjoy life whilst you're young- go out with friends, be sociable, make new friends and eventually you'll be in a relationship because if you keep dwelling on the fact that you've never been with someone, you might end up with any old guy which could end up being disastrous. Just take life as it is and you might be surprised.
However, if you really do want to find someone- I guess you're probably a nice person so just continue doing that, be outgoing and sociable, make everyone feel welcome & friendly. Don't pretend to be someone you're not, i.e. dressing up in a way that makes you feel uncomfortable in order to get attention from boys, being obnoxiously loud when you're someone who's normally quiet. There's no need to change the way you look or act in order to find someone- if you do & your crush finally accepts you, that means that the person doesn't really care about who you are deep down inside. Find someone who makes you feel like you in a good way.
Make sure that you actually like the guy for who they are as well, not just solely on their looks because eventually you'll get bored of them & it will be this vicious cycle forever.
Good luck, hope this helped
