text: gynecologists...? please be serious when answering!  i'm being serious, so should you.  my friend kim has an older sister named allison.  when allison got back from a nearby town partying for her birthday (she's 16), her mom took her to the gynecologist to see if she'd has $ex.  she hadn't. but my question is, how does a gynecologist tell if you've had $ex before?  if i've stuck something into my vagina once (i'm young, experimental, etc - don't judge me!), ten would it look as though i've had $ex?  honestly, i'm being serious and truthful, please help me by answering! a doctor cannot tell whether you are a virgin or not. what a doctor can tell is whether your hymen has been broken or not. a female can break her hymen in many different ways, such as horseback riding. also, some hymens have a large enough opening to accommodate a penis during sex so that the hymen does not tear. if you are concerned about a doctor inferring that a torn hymen means you are having sex, do not worry. it is not the doctor's position to make any assumptions about you, even though he or she might ask you questions regarding your sexual activity. for your best interest, you should answer your doctor truthfully. your doctor can better care for you if he or she knows all of your medical history, including whether you are sexually active or not. in addition, doctors have a bond of patient confidentiality with their clients, so a doctor cannot tell your parents if you are sexually active if you do not ask him or her to tell them.   http://www.soc.ucsb.edu/sexinfo/print.php?article=faq&refid=310  it is very difficult to know if a woman is still a virgin, even if there is tightness as a doctor examines her. there are many factors that need to be taken into consideration. for example, a woman's vagina may be tight because she is nervous while being examined by the doctor, or then again, her muscles may be relaxed and she may never have experienced intercourse before. a woman may also not have a hymen, and never had one, so this would not indicate her state of "virginity". the best way to know if a woman has had penile penetration still remains to ask her. most doctors will also ask their female patients if they have had sex before, when they are about to make a gynecological examination for the first time.   http://ideas.uqam.ca/~dsexo/english/9906e/qa0384-1518m.htm
