I didn't date until I was almost 20, I turned down (as awkwardly and nicely as I could) every offer that came my way. I didn't want to date someone I had not the slightest interest in. I finally met my fiance, we worked together and I really liked his attitude towards life, his general demeanor, etc. I also thought he was cute, so that was good. I bucked up the courage and asked him out. I was lucky, he's a wonderful man and did not have some other agenda. All I can say is stick to your guns, whatever decision you make with any man. Do not do something you don't want to do, or go out with someone you don't want to go out with, especially not just for the sake of it. When you meet the right one, you'll know. It was like electricity when I first laid eyes on him, growing in intensity as I got to know who he was, and I'm happy because I can look back and know that I was always true to myself.
I know how you feel though, I was starting to wonder if I'd ever meet him, hell, my dad thought I was a lesbian because I didn't fawn or chase after boys or go on dates. But in the end I'm really happy and we have a wonderful future ahead of us, I have what I wanted, not what someone else wanted or what I took for lack of willingness to wait, and that's how it should be. What YOU want for yourself, always hold onto it.
