Guys, what is it that attracts you to female or enables you to APPROACH her!?!? (I can't get the guys I want!!?

Ok so, I'm a 23 year old virgin & I believe it is b/c I am not attracting the type of guys that I would even consider having sex with. I'm constantly told I'm gorgeous & various other compliments but, I'm also told that I'm intimidating & not easy to approach. How can I make myself more easy to approach in club, bar, grocery store type settings......ya know, beside dressing HOT. lol And give me something other than "just smile" folks b/c I've tried that crap & I just look crazy!!! lol Help me!!!!! I really need to get this "virgin hurdle" out of my way BUT FIRST, I need the right guy (hopefully my future husband:)!!!!
