The girls in my office were talking about being a virgin. We were wondering if a guy can tell if you are a virgin or not the first time they have sex with you? If there is no blood, how can they tell? They were also saying that you get stretched out after years of having sex. Is this true? What if you don't have sex for a number of years, do you get tight again? Just interested

  Ever since women have become more active, riding bicycles and playing sports, more and more women are breaking their hymen before they actually have intercourse. If their hymen is broken, then there will be no bleeding the first time they have intercourse, and without that bleeding there is no way for a man to tell whether or not they are a virgin. All they can do is believe the woman.

I don't know about prostitutes, who have sex a dozen or more times a day, but at the frequency that most women engage in sex, they are not going to get stretched out from sexual activity. What often does stretch a woman's vagina is giving birth. Sometimes the gynecologist can add a few stitches right after the delivery to restore this tightness, but I don't believe there is any natural way for this to take place, though I am not a doctor so I don't know the answer for certain.
