Imperfections? For you or for her? If you're sporting anything over 5EG she does not have time to think about anything except
Dick during sex. (For anyone under 5EG consider this carefully: just because she's not entirely focused on your
Dick does not mean she is unsatisfied. Unlike you, she is not focusing entirely on your
Dick but on how attentive and a great love maker you are) If you are sporting 6EG+, let's face it she might as well be getting fucked by a fence post. At those sizes she's probably just trying to not get injured as much as she is thinking
Dick. She doesn't have time to think about imperfections. So do it for yourself, only yourself, if it is important to you.
Note: the 5EG size reference, and 6EG is purely hypothetical and will depend on a variety of impossible to pin down variables such her mood, her prior experiences, her current vagina tightness, weather, what she ate for breakfast that day. Etc.
