My 9yr old has no opening at the moment. You can see where it should be but its not opened yet. I was told she has a complete hymen and that it should open by puberty and if not its a small procedure to open it (at the age its more for AF to come out without discomfort then anything else) I expected it to open by now but it hasn't. I thought it was normal (which it is but not common) but the paed pointed it out when doing a complete assessment for another reason when she was extremely unwell.

As a theatre nurse I have seen several young ladies around 15 have the hymen opened takes seconds to do it so if your daughter has a small opening she should avoid anything like that as the ones I have seen in theatre have being completely closed. It doesn't affect the other parts of the reproductive systems and there still there and work normally.

Also as a midwife women have all different shaped labia's, vagina's etc. Some tiny to look at and others not so small. Even if she has a very small vagina and external female genitalia I am sure it will all function the way it is designed to. If I had to choose I think I would want a small one all neatly tucked away.

I would take her to the paed like you said you were going to and I am sure they could determine that she is fine down below or if its neccessary to have an ultrasound or followup when she gets older. If everything is there just small (urethra, labia majora, labia minora, clitoris etc) I am she is fine. If the parts were missing then their perhaps would be more of a concern.

If she is tiny down below the urethra is probably very short to the bladder so she is at greater risk of developing infections. Hope your baby girl is ok and you can prevent her from getting UTI's. Poor bubba.
