Can i know that fingering a girl can loose her hymen if there any way to fingering her without breaking hymen?

If a girl has a hymen, the opening is usually the diameter of a pencil. Anything larger inserted into the vagina will stretch or tear it. Sexual activity is right when it is a shared equal experience. It should never be given away or taken. It is best to leave this alone until you both share the desire to go to that point. The area is sensitive.

The size of the opening in the hymen is variable. It may be feasible to finger her without tearing the hymen but I concur with Dr. F that you should not engage in such activity till you are committed to each other, preferably married.
