OMG! BOTH. Think about it for a minute. What pleasure would there be if he was 1 inch long but fat OR 12 inches long but thin as a piece of wire? So for all the guys in here REALLY needing to know this the answer is definitely both. There is no either/or here.
i;ll take the splitting in half; as long as they are at least 5 inches in length. butt, its an acquired taste and one that takes practice at accommodating.
it is more how you use it I have an 8in long 5 width dick which I think is small but I can work it the few women that I have fucked like the way I move my ass and hit the right spots I do not try to kill the pussy I just work it over I like to see the girls lay back and say ooooooohhhhhh ya when I am done but I think four play(eating the pussy) allways help getting her nice an wet first when her cummm is ready to flow thats when you start to put the dick where it should be remeber not in the cirvics
