I'm not a guy but I can give some advice
For starters you can't make someone like you. And infact somtimes rejection can be a good thing. (painful sometimes but definitely good. It took me down a peg that's for sure)
Whatever you do, don't change yourself. A guy should like for everything you are (including but not limiting to your faults and short comings whatever they may be).
And PS:
you'd be surprised by the number of guys that don't respond positively to flashing or don't think sex. Same thing with streaking or mooning.
That's my two cent
oh and Fal:
tramps do get laid. The problem is the kinda of guy any
lady looks for is not the one that lays with a tramp.
and on that note, it's ok to want to feel and look sexy. However, there are certain limits to how sexy you should look in public.
