What do you think are the reasons why so many young girls act promiscuous?

I was promiscuous when I was younger not that I am old now I'm 22 and married. But if guys can do it why can't girls. If a guy does it he is a stud but if a girl does it she is a . Double standards. You have to experiment and feel your body out. If you were just with One person your whole life you would always wonder what its like to be with someone else
