The topic is "normal vagina". At a glance it appears to be a simple topic but when you attempt to define normal vagina, you are left with scratching your head. And then, the complexity of the topic sinks in.
What is a normal vagina?
Having inspected many myself, I consider myself an expert on this topic.
I would say "normal" is somewhere between and "innie" and an "outie".
I have known (in the biblical sense) one extreme "outie" and her name is Cynthia. Due to her extreme outie, she developed a drinking habit because she was somewhat shy of being seen naked while sober. It was a nice outie, but very bizarre. She lives in Half Moon Bay CA.
Clitoral length also varies, from tiny to very long. The longest clitoris that I have ever known was a female named Sherrie. She lives in Modesto CA. She was a bit shy about her nice long clit, but due to the pleasure it brought her she was very happy about it. Hers was about 1 1/2 inches. Normal is closer to 1/2 inch. Tiny is 1/4 inch or smaller.
Obviously tall females are going to be larger than shorter ones.
The main thing to be concerned with is fit. It's just like trying on a pair of shoes before you buy them.
Any woman that is "too tight" is going to have pain during intercourse and therefore sex will be self defeating as a bonding or pleasure issue. The only female I have encountered with this problem is named Linda. She never married. She lives alone in France.
Any woman that is "too loose" is not going to feel much and therefore will not achieve orgasm. In my entire life I have only known one female like this and her name was Debbie. She has a facebook page. She eventually found a very large beefy male around 6'6" and they have lived happily ever since in Colorado.
Ergo "normal" would be "proportional" and "moderate" between the various extremes.
