From the considerable amount of porn I’ve seen, none of the men with exceptionally long penises are ever able to put them fully into any vagina. They are only able to get them fully into a woman anally or with a talented deep throat artist. From what I’ve read, the average vagina can only accept 6.5" of insertion. ---

I, a male, have been in a semi-unique position to speak very frankly with quite a few women about this. What i have learned. For most women average length/width fits great, nice contours (everyone has a fav) make it special. Gotta hit the right spots. For a few there are size/comfort limits, just above or below average. Then there are those who want a porn star…you know, built on a WAY different scale. On a related note, the one thing that disappointed them the most about the intercourse itself…no cardio training. If you can’t breath you can’t be reasonably active, and sounding like you’re going to die after 5 mins was reported as a turn off even if everybody got theirs. ---

more science: describes mri of missionary and rear penetration also discusses previous efforts There is a common theme of the penis usually going into the vaginal fornices (arches), either anterior or posterior to the cervix, depending on methodology. The mri study had the penis in the anterior fornix for missionary and posterior fornix for rear-entry. I’m afraid I may be overquoting a bit here, so I only post the second (missionary) and third (rear) runs; the first run was a “dry run”, to demonstrate the undisturbed anatomy. They do show significant vaginal stretching to accommodate the penis.

Once a week for a few minutes? Like a few hundred minutes a year.😕 I’m an average guitar player.
