I don't try show my feelings all that often (though sometimes I do unintentionally).
I don't talk about my feelings unless either I need to because there is a conflict between me and someone else, or if sharing my feelings will benefit the other person somehow (for example, helping them better understand a common issue I happen to have).
If I do share my feelings, I always do it through the internet. I feel a lot less vulnerable, and if their reaction is negative, I don't have to see or hear it.
Bottom line, though, I value the talking about feelings over the showing of feelings. It's easier to know what's on someone's mind if they talk about it instead of me having to judge so.
