It's like this from both guys and girls.
Whilst the idea to some seems fun and exciting, it's okay - but if you really do want to find someone that may be serious then trying different things that aren't you won't work I reckon.
I dunno, from what I've read from people quoting stuff from these guides, I reckon its far to general. It maybe good for a "quickie" but if you're looking for something pretty long term and possibly more meaningful then there has to be something between two people beyond the looks/charm - interests, tastes, experiences.
Personally I reckon talking, being nice and polite with a hint of flirting goes a long way than dancing about, rolling on the floor and saying a bunch of stuff they've heard a million and one times before - well, unless that floats his/her boat.
