Is it sexist no to date women my age?

I only like to date 22-24 some time ill do 21 but it's rare.

I'm 29 now and women my age have nothing to offer me. I often avoid them.

I only ask because I had a girl flirt with me at the bar and she wasn't that drunk. But she had to be my age or early 30s. I kept the conversation friendly not to be too rude.
