Force yourself to talk to girls and be nice. That is about all it takes. Good luck!
Talk to girls! It doesn't have to be face to face, message them or something, but don't be overly annoying! If they don't reply, don't sweat it. If they do, keep the conversation on them unless they talk about you. Just don't send a message over and over. If you talk to someone face to face, be nice, be yourself.
Just talk to a girl! It could be a crush or just a friend. But it is completely usual for most of your friends to be boys.
Coming from somebody who has a lot of friends that are girls. I would say just find a girl that likes something similar then talk to them about it. Use courage.
As hard as it is, you really just have to let yourself open up so girls can really see what you are like so they can get close with you.
Well I say go for the girls in your class and see which one you have a lot in common with and then become her friend and then become her friends friend and so you go then you have a lot of girl's to talk to.
How about trying to running background check on the girl you are particularly interested in and work on that, good luck.
