Honestly showing affection to others is quite difficult.
It takes years for me to openly state "I *cough* love *cough* you" and when i do its in the form of a tease -.-.
I was raised be an ENTJ mother, and she doesnt give affection much also.... If i give hugs its awkward... like y'know that hug at the end of step brothers between the brothers....
... anyone know what i mean?
