Trouble finding the one

I'm 14 and in 9th grade. This year I realized that I was Bisexual and I would like to find a girlfriend. The problem is, I'm still nervous about getting one and I can't seem to find any single girls who seem my type. Not to mention, I also don't really know who is in to girls like I am. Ive had plenty of crushes but when I get to know them, I realize that either a) they're straight/taken or b) they aren't the person I thought they were. Any suggestions to finding the right girl???? Any help would be appreciated!!
