Yeah I don't think there's anything wrong with only wanting a physical relationship, as long as you are upfront about it. I think the difference with most people is that they aren't upfront about it, and so their frustration with the 'friend zone' is probably mirrored in the other persons frustration of the 'fuck zone'
I think both of the scenarios you listed are harmful but I also think that the guy could opt out any time, but doesn't in the hopes that it will lead to more.
I also agree that a guy can be strong and dominant and be emotional and caring at the same time. Basically what I am saying is that our society teaches men to suppress emotional expression to fit into the role of strong and dominant so a lot of people are left knowing that being honest with their feelings can be looked down upon. Women also learn to want to be with someone who is dominant because of the way they have seen relationships expressed and because of the way they are told to fit into the world. It's great when people can break out of these expectations but I am saying that they exist and could possibly result in this 'friend zone' which is due to what women are told to want in a partner while it may not be what they actually want.
