19 or older and never been in a relationship

I am 19 and have never been in a realtionship, i think this is pretty odd as most people my age have been in some sort of relationship, im not being big headed but im pretty good looking 😂 and have been told that i have a great personality, i will speak to guys and get on with them great but i am never the one they want to be with, there is always someone else they want or they 'dont want a realtionship' and a month later they will be in one.. it doesnt always bother me, being single can be great.. but some times it makes me feel really crap and makes me feel rubbish and insecure about myself and the way i look 🙄🙄
