You're right, it's sexist.
But true.
If I didn't meet someone soon, I was not going to bother looking anymore. As much as I wish it wasn't so, most men meet a woman with their eyes first. Plus the older you get, the less desirable you are and many go after the young chickiepoos. I've been around the sun about thirty times and even noticed girls younger than me getting more attention. It sucks.
