Check out the stuff by Ross Jeffries.
He has this 'Speed Seduction' techinique that REALLY does work. It's loosely based on NLP techniques) He's a real arrogant/[censored], but his stuff works so he's entitled to be a jerk.
I have some of his tapes and CD's. I'm a real skeptic but honestly, his concepts and techniques are very effective. I use his techniques in a more 'passive' manner.
And, the 'speed seduction' techniques can be used in other situations (like influencing co-workers)

It's a totally lame site but has a lot of info (if you buy into his theory)
