I’m not sure I’d agree with that. An 8 x 6 might be too much for a quickie with some women, but how much is actually “a lot of foreplay and/or extra lube”? Most women would get pretty wet looking at such an organ, and even wetter sucking it. It’s not like most women would need 45-60 min prep time to get it in. And what women in the world want 3-minute sex?
I honestly think there’s some validity to what Modesto man said (sans ice age caveat). I think that a small dicker keeps most men in check (I know there are exceptions - i.e., big-dicked shy men and little-dicked whores), but for the most part, most men would be quite embarrassed to walk throughout their day naked. And that big-dicked guy I went to school with did nothing with his life. He was not a worker bee, but spent all of his vitality spewing his seed everywhere. Never held a job, started a family or took care of anybody but himself. I think a lot more guys would be like him if they were packing 10 (NBP) x 6.25.
