A woman who's older than I originally thought is enjoying going out with me, is that unusual?

I'm in my 20's and asked out a woman I have a crush on, she looks so young that I assumed she was also in her 20's like me. I found out on our first date that she's actually 36, I thought me being 25 would make her uninterested but it didn't. She said she had so much fun and wanted a second date, she said she had even more fun and now we have a third date.
