Suit yourself, I find the erotic moaning of especially japanese women a huge turn on, much better than the "talking" most western women do during sex... As someone who has been in orgies nothing kills my boner quicker than hearing a sexy blonde milf telling her husband "yeah shove that huge cock in there" and the dude is 3.5 inches long... My brain cant process what she is doing... is she mocking him ? is she encouraging him by LYING ??
Granted this isnt a shot against guys with below average penis, 3.5 and above will allow you to please a woman just fine if you KNOW what your DOING. I mean the average vagina size (how deep it is) in the USA is 6-7 inches, so guys that like to brag about their 13 inch dicks guess what ? half of your man meat is gonna be waiting outside, unless you ahve one of those squishy penis that even when hard can bend and mold, than you may get more inside ??
Back to the original point, girls "talking" depending on what they are saying can be a huge turn off, I'd rather western girls did more ohhhhss and aaahhhs and some mmmmm's thrown in for good measure rather than here "yeah you like that baby ? huh you like that ?? answer me !!!"
