I'm rescinding my previous post.
I'm not one to edit out posts that have already been read, but I take it back. It was meant to be sarcastic, but it wasn't fair, because I was interpreting the preceding statement (about how women prefer men that express their emotions) too broadly.
I suppose it comes down to what expressing emotions "in a mature, appropriate way" means to the individual woman. For me, it means expressing them rarely and briefly, and if that makes me look like a robot to a woman, then we're not meant for each other. But as Paradox here and others in private have noted, not all women are like that. I just haven't met any in person who like non-emotive men.
And by the way, just because a man doesn't emote doesn't mean he suppresses his emotions. Emotions aren't physical substances. They CAN be dealt with internally without building up pressure like steam. I can find something amusing without LOLing, and I can be grieved by something without shedding tears. If I think it warrants involving other people, I will tell them. But in general, I find my emotions to be irrational, and acting on them to be improper; and I don't see any benefit, for myself or another person, to expose that other person to them. And for that reason, I find emoting largely to be a waste of energy best spent on something else.
