It seems that size is not as important as what a man can do with what he has. Some women like them bigger, some like them smaller, some thicker, and others thinner. My experience is that if a guy pleasures a woman to orgasm then, his cock is just the right size. If not, it probably doesn't matter what size he is.

It's different for every woman. But generally, I'd say anything over 5.5" in average girth and 6.5" in length (measured properly!) would be very pleasurable for most women. Anything much bigger than that could feel even better- if the man is skilled enough to use his extra size for pleasure instead of pain.

If it fits its the perfect size
