thanks from your nice reply and thanks from your encouraging remarks about my penis size.
Do you imagine vaginas are endlessly long? Speaking as a woman, too long of a penis can make for an unpleasant experience. The man's penis will hit the woman's cervix (at the end of her vagina), and that hurts. A vagina is only about five inches deep. Basically, someone with a freakishly long penis would not have a "long, deep" penetration, he would have five inches of penetration and the rest of the penis would be out in the air, and his partner would be saying, "Ow! Quit bonking me!"
Don't worry about a thing. The nerves that are exciting during sex for the woman are all in the lower third of her vagina anyway, further back there are no nerves, and the clitoris is right at the vaginal opening. It's what you do there, that counts.
