Even if she is describing what you are feeling (saying how good it feels when you hold her, etc), it's still not safe to express feelings. It's not even safe to say you feel the same way.Every single time in a relationship where I've showed significant feeling/emotion it has come back to bite me. By no means did I go overboard, I was simply being human. I think there's a double standard out there and sometimes feel guys aren't allowed to express themselves fully. When they do it is seen as weakness.
Are we really supposed to believe that our ancestors felt zero emotion, ever? Did women always punish men for being human? Is it the key of feminism, the idea that men should be infinitely strong? A man who shows zero emotion ever is called a Sociopath.
In the past, I think the bond women felt when they had sex was stronger than the loss of attraction they felt (if they ever did then) regarding him showing occasional emotion. I think promiscuity is the cornerstone that underwrites this horrible female philosophy.
I can see how a man shouldn't always be emotional, but when women want to be like "AHA! I saw you care about something!! You're not infinitely strong! No second chances!" it's almost pathological.
