That question is what inspired my quest: http://www.lpsg.org/142661-how-deep-is-your-pussy.html
I've been obsessed with the cds orgasm for ages and this poll brought home an important point for me... I am truly blessed. I'm not long by any means, but combined with her depth, we match perfectly. My wife's most intense orgasms comes from a blend of the deep spot and her clit being stimulated simultaneously. She can do this when she's grinding away on top of me.
Now, down to the numbers... I actually measured my wife's depth and she's 6.3" deep (based on the measuring method from my survey). I'm 6" nbpel, 7" bpel. Projecting those two numbers out, and assuming that I am stimulating her cds perfectly (footnote 1), I've come to the conclusion that you need 3/4" more penis length (bone pressed) than vaginal depth. This is due to two factors; glans squashing and amount of "give" from both vagina and penis at the bottom to press down hard.
Based on the survey results and making an already faulty assumption that those numbers are legit (they can't be, this is the internet), the average aroused depth comes in at 7.1" making the ideal penis length 7.85" bone pressed.
Asked and answered. Bet you weren't expecting a solid number, where 'ya?
Footnote 1: She's mentioned frequently how she can't rub that deep spot for extended periods because it gets sore. Proving that there are nerve endings that far inside her and that more length from me is probably unnecessary.
