Are you good at guessing age?

I was at the bar the yesterday and tried to talk to as much people as I can. Many times when age comes into the topic, girls want me to guess their age. Now, I like a good challenge and apparently, I am really (really) good at guessing people’s ages to their surprise. I understand that it could be a conversation starter, or that it could be curious to know how old you look like.

Well, as I think back to my interactions, I realized that many of the girls I have met even before this wanted me to guess their ages. Should I just flatter them next time and shoot lower than my estimate or should I stick to my guns and never take a loss (even my virginity lol).

I had great interactions overall, just wondering how you guys deal with the age-guessing game.
