As a well endowed male I will tell you what one of my ex's told me, when we first had sex she could not take all of my penis but once her vagaina got used to it she took it like a champ, last time we spoke she told me that her current boyfriend is great but she is not getting that filled up feeling in her vaginia and she misses it so much, once a girl gets used to a big dick she never wants to go back.
