This is one of those questions that is pretty hard to answer, as its hard to explain emotional response in words. I agree with the postings on sensuality, but i think it is far and away past anything tactile. A feminine trait is in doing things simply because you want to; its pretty, feels nice, makes you happy, sounds nice, smells good, etc. The "masculine" mold seems to be in logic and practicality, and being concerned more with gain or usefulness than simply enjoyment of the moment.
It is beyond physical. Feminine expression, through art, music, conversation, or interaction with other people is driven often by what feels good, not by what is prudent. Whether it feels good for themselves, or others, or for no one in particular, simply because you want to.
Basically, the freedom to do something because you want to do it, because its something that pleases you, or is new, or looks fun, or is soothing. Im not saying that some men dont find this level of personal contentment, but most men (not the ones on this forum) would not wear a corset, simply because they like how it felt or looked, and it isnt "practical" to buy something that has no real purpose, other than how it feels or looks?
Being feminine also means a level of self confidence that dosent need any sort of concrete, tangible "things" to keep it intact. Reading a book, looking at a tree, wearing a new pair of shoes, is its own reward, it dosent require someone else to quantify its value with compliments or praise...or money. (though, no one, man or woman, minds acknowledgement of their choices. Men just seem a bit more hung up on it)
Maybe being feminine means being more primal than men, overall, if that makes sense?
