Kinsao,
I like that a lot:
Personally, I don't find so attractive men who look too fragile, simply because, they make me feel clumsy by comparison, and if someone makes you feel underconfident in yourself, it's difficult to be attracted to them, right?
I would like to say smth in addition. No need to argue it is good the man to be gentle, but it is very important to keep in mind that the tenderness of some men can make them look somehow weaker, which, personally me, makes me feel like I won't be able to count on this guy in life.
Here is one interesting experiment made by some scientists who have searched an answer to the question "What makes one woman be unfaithful?"
The test is made with a few women, half of them were in such period when they were able to get pregnant, and the other half were not. They have been shown different men faces - which were spread from very gentle and mild to let's say rough men's faces.
The results have shown the first half of the women liked much more the men with rough characteristic faces, while the others liked more the feminine men's faces.
How do they explain this? The deep women's instinct tells the woman to choose the stronger ones, b'cos as Charles Darwin has once long ago said, the strongest survive and are able to best fight life

and of course every woman wants the best for her child. So the best would be a strong father who will be able to ensure good cares for his child.
Nowadays, it seems the mark which makes one man strong and winning confidence is the man who has very good material status.
But in spite of this I don't think that the natural human instincts are going to just dissapear or degenerate totally in smth whatever else - for which the above test is a proof.
