Why the hell is every guy so obsessed with having a long penis these days? It's not the length that counts as the average vagina when fully aroused is only around 5 inches deep it's the girth that matters more a guy with a 4 inch long penis with a thick girth can give a woman more pleasure than a guy with a 7 inch penis that has a thin girth, it also comes down to how you use it as well to give pleasure and not just copy what you see them do in porn movies because that's just fake.
Learn to use what you have and you be surprise at the results.
