I need a significant other ;-;

I (17f) feel so lonely and I want a romantic relationship so bad.

I'm homeschooled so I don't get to meet many people, and I grew up with a very small friend group of only girls and I have no idea how to talk to boys.

I blush when I talk to any boy, also when I'm not even remotely attracted to them.

There's a few at work I really like but I'm pretty sure they both have gfs or just aren't interested.

In also Bi and am interested in some masc girls, I almost asked this girl out the other day but she was with her family and maybe a friend and I wasn't about to go ask infront of everyone she knows bc omg

Any advice is appreciated :(
