Hi mgd,
I’m probably going to get in trouble here, but I’ve been experimenting against this situation, and for you I recommend this combination to rid you of the “nice guy” image. Use Instant Jerk with Turn up the Heat, combined with your favourite cologne. When I use these together I certainly feel like a wild child and flirt like crazy.
The suggestions above are good too. I suggest you read about all these products in The Mens Guide
Good luck and do return and let us know about your results
