I don't understand the interest in mine. Girls will compliment them, poke them. And demand i smile. Why is this cute to them? Is this something that are taught is cute, or human nature decided that it is attractive?
You might not like the truth. Dimples remind of the lines in the face chubby babies have. People are hardwired to go "aww" over anything baby like. It's almost within everyone. So when you smile, you trigger the cuteness program in them.
Your height might also increase the cuteness factor... But don't worry, it's not necessarily bad for women to think "cute babies" when they see you. Their instinct could tell them to make some cute babies with you, if you get my point. :D
