Almost 17 but i nvr had a gf...?

first of all, im not ugly i kno that for a fact, i think im good lookin, but it feels like girls dont wanna talk to me, i get stared at by girls in my school. idk whats goin on? why wont girls approach me. i am kind of on the shy side, so most likely i wont approach a girl. i used to be confident but when i moved to this new school my self-esteem dropped, because i made barely any friends. sad thing is i have been here half my sophmore year and now my junior year
