Feel lost in adult relationships?

When my sisters kept getting dumped by losers, I always told myself that wouldn't be me. I wanted to live life on my own terms and not get screwed over by some guy who wasn't even worth crying over. I met a few men I was physically attracted to but I didn't go any further with it. Now, the thing is I'm 23, as I feel so far behind everyone else with all their disastrous relationships. I feel as if I'm ready now to have a fling since I'm meeting men I find both attractive and interesting, but I have no idea what to do? I feel awkward around people (especially men) when they ask me about my past relationships. I tend to give off the impression that I'm sensual, artistic, and slightly wild, so they're expecting, I suppose, that there's be at least a few men in my past.
