Female wrists, hands and fingers are naturally narrower and longer, and I believe are .... well, more feminine. In spite of a previous comment, pen pushing and beer can subduing were not a standard use of male arms and hands. Try plow pushing, axe swinging, weapon handling, hand saw useage, rope climbing, etc. None of these are great for dainty hands. Hand pampering and moisterizing helps as well.
That said, you do not need to engage in swishing behavior to compensate. I've always had, if not dainty, at least less than ham-like hands, and I worked my whole career moving things, boxes, luggage, steering wheels. I have done flexing and stretching exercises for years, which helps. It's all part of the study process. We watch women for walking, sitting and other mannerisms. Just watch their hands as well.
