Question for men? Story time

Last night I was at a bar dancing with a guy and it was fine than I asked him for his age out of curiosity and than he asked me for mine. Fast forward he was 23 and I am 30, haha after this happened he wanted to stop dancing with me lol. I mean I think I look great and maybe even younger I have been told many times but what the heck haha why are men so afraid of numbers? I don't get it.
