Why am I still alone??

Ok so I have never done anything like this…go easy on me. 😉 Well I am a 22 year old female about to graduate from college. I have never had a boyfriend! 🙁 It’s not that Im unattractive because I have had plenty of admirers and dated people. I have also been in sexual relationships. Now when I was younger in junior high I had a few boyfriends(I don’t count them)….after high school I “talked” or dated a boy that I had very strong feelings for. Everyone refered to us as a couple but we never made it official. The reason was because I was soon going away to school and neither one of us wanted to do the long distance thing. Well eventually I got over him and talked to other men. Someway or another we always fizzled out….Now I am back home and live in a small state. Most of the men here are not checking for me. 😯 There could be many factors that play into this: 1.) A lot of guys around here prefer one type of woman (physically) that I do not fit into. 🙄 2.) I have been told from various people that I seem hard to approach at times. Now the guys that are checking for me are usually the ones that I define as lame. 😆 When I say lame I mean they either are lacking swagger(confidence) or are unattrative or don’t have much going for themselves. I know that I am picky but should I lower my standards just to experience love? Another problem that I have recently developed is getting “shy” around men that I find attractive and who begin flirting with me. 😳 I think because I have been alone for so long I don’t know how to flirt anymore and find myself somewhat uncomfortable in those situations. My friends say that I am too picky and don’t go to places where I could meet single attractive men. 😕 What do you say?
