Is it any validity to the idea that, on average, white men and black women have "more intense orgasms during sex (in comparison), because white men, on averaqe, have a thicker penis and black women, on average, have a more condensed lower body?

No, there is no validity to your Q, the race of sexual partners has no bearing on the intensity of orgasm. Even if they are of differant races.

what an interesting question. I had two white wives and three black girl friends, one of which almost became wife number three and I can honestly say that my second wife was the hottest woman I've ever known and she sure as hell wasn't black.

The three black women, however, were the most exciting for me because their vaginas were the smallest. With a seven and a quarter by seven inch penis I never met a woman who was too large but the difference in size between the black women and white women (I screwed around with about a dozen others) was extremely quite different and exciting.

I mention this because of the so-called scientific
evidence that black and thin women have larger vaginas. Two of the three black women were thin.

Since I'm white I have to laugh when I read the so-called penis size surveys. I don't consider myself much larger than the guys I grew up with, all white, yet at 7 1/4" in length I'm supposed to be larger than 85% of all the white guys measured in these surveys and there is even a greater difference between my circumference and the "average" white man.

I'm sorry, but there's an awful lot of 9" plus white guys out there. In fact, I had sex with a woman who'd been married to two men, both white, who possessed 9 1/2" dicks. They must have been skinny shafts, however, because she anjoyed the hell out of my shorter one.

i am a white male....i had an african american girlfriend, and many white and mexican girlfriend's......it is pretty much the same......as far as sex goes......take care....Brian.....

Nope.
there is no validity to any generalization even the one i just made.
Which is a conundrum in a sense.

Depends on the individuals.
