I think I've just discovered something. Could sound kinda stupid but it isn't.

Love IS sex. In every meaning, size and color.

Being "in love" only means that you want to have sex, and mostly with only one person; that person. This is exactly what the barbarian do. They complicate things in order to live in their little lives without any possible shame. When you are civilized you simply CAN distinguish those two things: heart and penis.
And all this time they made me think I was the outsider... when my biggest mistake was to see things more clearly than the others.
Maybe I should create a new word to express myself properly.
