I know where the vagina is, but I can't seem to find it on my body. There is no visible "hole" that I can see in the area under the clitoris, but if I put my finger up between the inner skin and the outer skin at the bottom, there is a passageway that my finger can fit through. Although it's not visible, is that the vagina? I am somewhat worried I may have an imperforate hymen. Also, is it because I am a virgin that it is not as visible as others?
