I went I looked, and it was hard to drag myself away from the picture of you fucking the woman. And it is difficult to actually say just from the pictures.

But your cock seems to me to be perhaps a bit longer than average. Average is just short of 6 inches. But about average in diameter. She seems to like it, and that is about all that is important. It works to fuck the women, and more or less is not important.

Measuring pics, else it's all guesswork.
