Situation:

You go out for a night of clubbing, and see a woman wearing a short dress, sipping a martini by the dance floor. You overhear her talking with her girlfriends, and she states that she has only slept with one guy her whole life, and her girl friends are shocked to hear this.

Would you believe this woman? Would you believe any non-religious woman who is 28 years old and said she only slept with 1 guy? Why or why not?
