Yea that's because they're a "no threat". If there's a chance they might actually attract a real man they behave differently. A neutered metro/homo/whatever is completely another matter. Then they're "relaxed". Or whatever.
I think I'll go with the "subconsciously like evidence of gonads". Eventually, if nothing else.
Weak women prefer men who are weaker than themselves, so they can feel "powerful" like the feminists tell them they're supposed to. Also, they've been taught that every man is a potential sexual predator, so again they prefer a weak man. If said weak man also likes shopping and foreign films, she'll take the Metrosexual and the (sexual aid.)
Real women (like my wife) like real men, the powerful, protective kind. And she's strong enough to stand up for herself in any situation. If I may be so bold, she also doesn't consider male sexuality to be something alien, horrible and disgusting. Quite the opposite, in fact.
That is actually a symbiotic relationship. Both like nothing better than talking about their feelings.
It should give any straight man pause...
