This is the most important reason why you should never believe people who say that the penis size issue is just as silly as the breast issue! It is here that the comparison of the big breasts versus big penis debate fails: the actual sexual satisfaction during intercourse. (For the smart comment makers, tit fucking is not considered intercourse, even if some like to call it inter-mammary intercourse.) Although it might be a huge turn-on to see a couple of big jugs springing back and forth while giving it to your lady, it doesn't cause any more penile sensations for you.
