I don't dress warmly enough because I hate the bulk of all those clothes and do not expect to be outside where it is cold for any length of time, if I can help it. It's like umbrellas, who wants to have to bother!
As far as being manly, I "expect" my man to keep me warm at night, psychologically and physically; to kill the bugs that are too big for me, psychologically and physically; to pick up where I leave off like I pick up where he leaves off and just generally, to love me more than life itself
