Gigi, do not be afraid of coming too strong to someone that can be a potiential friend. The rules that applies to guys also applies to girl as well, just different tactics are involved... Find a guy that you find attractive and talk to him, invite him somewhere to continue the conversation.
Also, unless you are WANTING a jerk and an asshole, then the guy is probably thinking "I wonder if she asks every guy she meets for his number" or "she's desperate" and who gives a damn what a jerk thinks?
What you are after is that diamond in the rough, the nice guy with a spice in his personality, someone that adds flavor to love and keeps things exciting. In order to find someone like that, you need to dig and search for him.
