Or they just never got any offers. Not that I would know…
I know that when I was a young woman (a little younger than you), I seemed to be more or less invisible to guys. Nowadays, I suspect that my wardrobe of FLDS-escape type clothes did not do me any favors–if I showed you my clothes from that era, you’d laugh and laugh.
With a bit of time, nicer clothes, nicer hair and makeup and a bit more social self-confidence, the guys started appearing.
Plus, you’re working at a school. Unless you’re Florida Woman, that’s as good as a convent with a 10 foot wall. (I worked two years at a Russian school in the Peace Corps after college and didn’t date at all and didn’t get any offers, either, unless we’re counting the foot-loving pervert that I once encountered while changing shoes in public after work.)
I also think that some people aren’t destined to date a whole lot, just because they’re a bit unusual and won’t have a lot of interest from people who aren’t a good match. My dating career was (compared to a lot of people) pretty brief. Before I met my husband at 22, there was roughly a one year period of me dating (from 18.5 to almost 20) a grand total of three guys. That yielded: one coffee date, one month of dating and one roughly half a year period of dating, which lots of marriage proposals from the last guy. So, I dated only four guys total and two of them wanted to marry me. And I’m not exactly Natalie Portman. You might be the same way.
