I almost never tell girls my feelings. I get them to talk about themselves, but I keep most of the conversation to a banter. I only tell my closest guy friends my feelings.

A lot of girls that I've hooked up with have told me "it's almost as if I don't know anything about you", but they always say this with affection.

Whenever I open up to a girl and tell her my feelings, they lose attraction quickly.

So I posit: is being emotionally unavailable a good thing, and how does it relate to "vulnerability"?
