I suppose this is more in regards to guys. For the females, hurling yourself at a guy probably is a fairly effective way of getting his attention.
Western media might not be exactly be best source either. (Though a well placed "as you wish" can be quite effective )
However it seems like anime is extra bad. First of all in virtually all Seinen and Shōnen anime I can think of the female(s) basically hurls herself at the guy. Usually with zero effort on his part. Even in the more romance based ones without aliens or such.
However I don't know that the ones targeted to females are much better. I kept hearing about Vampire Knight, so I watched a couple episodes and read about the rest.
It seems the vamps make the ladies swoon. But all they seem to do is be emos and generally ignore the female(s). Possibly throwing a bit of being mean/violent on top in Zeros case. It probably helps if you're actually a vampire, but the few guys I know who went down that path only met sorrow until they stopped.
Anyway I occasionally hear snippets that Japan has some serious issues with marriage and birth rates plumeting. I wonder if this could be somewhat to blame?
