I'm too self-conscious around men?

I can't help but think of the possibility that most men aren't attracted to me; especially the guys that are good looking.

How can I get over this? I like myself, but I'm not conventionally pretty.. and I don't know if the guy would be embarrassed if I'd show my interest/ flirt.

I've dated before, but nothing serious.. mostly ended because it wasn't what I wanted

Forgot to mention that I'm pretty serious most of the time, I'm not boring but mostly just stressed out with school and stuff. It's hard to open up to people around you when you're busy like that.

Flirting seems to be something I haven't really mastered yet (I'm a bit shy) and well.. yea. That's it.
