how to know simply whether a grl is virgin or not...?

And I would ask you why is that so important. Would you not believe her if you ask and she said yes? If you didn't believe her then why would you be going with her. And even if she was not is that grounds to not want her? Are you a virgin? This is the one question a man should never ask or insist of a woman. It is truly none of your business.

can not you may know this by proceedint to lady docter

the man should ask if the girl is virgin or not because......if the girl is truly true the girl will say personaly that she is not a virgin anymore....
