Help with dating?

I'm 21 and I've never had a proper relationship - literally everyone I know has and it makes me feel like there's something wrong with me! I had a boyfriend when I was 18, it lasted 3 months (and was a disaster.) I've never even been on a date. I feel ready to start dating but I lack confidence and find it hard to talk to attractive guys (I blush really easily also.) I am considering trying online dating but I have no idea what to stick on a profile and I also hate taking pictures of my face (I always avoid cameras so I don't have many pictures of myself.) Any advice?
