a HUGE turn on for a guy (from a guy)

Girls, guys just LOVE so much when a girl smiles with only one side of their mouth, this is very sexy and makes you look a bit misterious. also, if you can, raise one eyebrow when a guy says something intrigue or intersting etc, its too bad that not so much girls know about it - but the combination of the two (eyebrow and single-sided smile) will make him think of you for a long time after that!

Hope i helped, cheers)
