This is one of those things that no girl will ever admit to, but underneath it all is true a good chunk of the time.
Best thing you can do when you want to know what girls are into is to NOT ask them (because most of the time they come out with a whole ream of BS lol) and just pay attention to the men they date. You want to know the kind of guy girls date? It's simple, took inventory of the girls around you and get to know/observe who they are dating.
