Im 19 and I've never had a bf?

just yesterday, I realized I'm already 19 and i dont have a bf. It kinda made me depress a little. ik its not the most important thing in life, but i want to expierince teenage love and i never got to. I know im still young but i wont be young forever and I'm scared that I'll blink ill be 30 and still alone. I was at work and it was really slow so all the girls just started talking. They talk about drinking and parties they go to and how some of them almost got arested blah blah blah and they all have bfs and they are my age. I dont do any of those things that they do. i believe in sex after mariage. I dont like drinking i dont do drugs and i dont party. I go to movies tho and hang out with friends. I just dont like doing activities that might involv death or ruining my life. I'm kinda shy I kind of have a baby face. People say i look 12 and find it hard to believe that im 19. I have had boys ask me out tho. But its mostly imature boys that do nothing but video games and would take me on a date with their mom driving us. I had one guy ask me if i wanted to go on a date to the carnival with him and he told me to bring money incase i wanted to eat or get on the rides. SO i have had guys ask me out but i turned them down cuz they didnt have what i was looking for. I always end up liking really nice cute/hot guys that either over look me or have GFs already. What do I have to do to get a good guys atention? what do the other girls have that I dont? I know im not ugly but I'm not drop dead georgeous either. is it because I dont party and have free sex ? cuz if its that, im probably gonna be single. What do guys look for in girls? Do i maybe have to change who I am??
