My surgeon was Dr. Preecha, I achieved 6" of depth (there was no skin to use for my vaginal lining, its all colon), but I totally agree with Brina about the width.
Successful intercourse depends mostly on your width, if you are lacking the width you need, you won't be able to take anything. If you can use the biggest dilator in your set given by your surgeon, you should be able to accomodate most men. If you achieve around 5 inches of depth more or less, you should be fine, thats enough. If you watch straight porn, you will see well endowed men can't put it in all the way. I know some people on this forum have talked about natal vaginas stretching more than our ones, but they can only stretch so much, they have organs restricting the size they can take too, they have digestive tract plus the cervix to worry about. A guy with a long penis will hit a woman's cervix and it will be painful. So I would not worry too much about other ts women bragging about their depth, a lot of women exaggerate their results as part of ego. This is not a big dick competition, the important thing is the individual can have comfortable intercourse once they have healed.
