As a straight male I do call boys 11 to 14 years old cute.
I find a lot of 11 to 14 year old boys cute in a non sexual way.
My uncle would also call other boys cute around those ages as well.
Some people have a baby face and look so cute even when older.
When I was between the ages of 8 to 16 I used to get called cute a lot when in public because I looked younger than my age when looking at my face.
