How can you stop playing it safe when talking to girls?

Anonymous
My problem and the reason I am 20 and never had a girlfriend is because I cannot flirt or make the conservation with girls more sexual. I only talk about boring things like school, wheater etc.
I see some guys, forexample at parties and other gatherings they'll overstep boundaries and say things like you have a nice butt and things of that nature and the girls will just slap them back in a playful manner and flirt back. They just dont give a damn, they say what they feel and make their intentions clear wihtout any filter. At the end the girls always goes back home with them.

I just have an inherent fear of talking to a girls in that way and thats why I always end up as the guy you have nothing against as a person but that you would not want to spend any alone time with never mind date or sleep with.
How do I get over the fear of saying things I'm actually thinking to girls and not play it safe all the time?
