Do 30 year old men prefer 20 year olds instead?

Anonymous

went on a date with a 29-30 year old guy, he assumed I was much younger than my age, he thought I was as old as his sister who is 21 but I'm actually 31, I felt that he didn't feel good about my age, he asked what year I was born twice, he was surprised to know my age but I felt like he didn't have much desire towards me after knowing how old I really was.

Iv had relationships before and always knew if a guy did like me or not. But I felt that this guy just didn't have any desire towards me after knowing my age.

What do you think? And please no sexist or mean comments, thank you.
