You've gotten good advice from the other so far, I'm going to take it a little further if I may.
Be glad that they have not contacted you because they'd only come back for seconds and not respect an inch of you while grabbing for more, and they would probably pass your number on to others who are looking for an easy girl. Do you really want to be treated like this?
Growing up and wanting a perfect and steady boyfriend is not easy and you should never loose your self-respect just because you think it would be cool to be 'together' with someone so that everyone else can see that you are not alone.
When you go out to places where people meet just once a night to make out, you are looking in the wrong place for the 'right guy'. Try a bowling alley or mini-golf, or entertainment park with friends to meet others that stay out of one-night places.
Believe it or not, most single grown-ups that go out to discos and make out on the first meeting are not serious about a partner either, so don't get caught in that too early in life just to be disappointed.
Good luck in your new chapter in life dear.

It's never too late to change a dumb habit.
