what im saying is common sense. you provided no scientific proof other than referring to your 4th grade curriculum. not gonna try to insult you because i have a different opinion.
its not "common sense" and you're a gott damn fool. I Pukokeki is right and you should listen to him.
You wouldn't ever fuck a girl who has given birth to a child before? What about Halle Berry?
Let me learn you somethin' son, I put it down on a 32 year old asian female who gave birth to 3 kids... and she was far tighter than this half black / half italian skeezer I smashed like 2 years ago (drunken mistake), who has 0 kids.
The Kama Sutra (if you ever read it as opposed to stare at the photos) suggests that you find a sexual partner who has genitalia that matches your [size]. I think they give each gender 3 sizes and name them after animals I can't recall right now.
Now if you abuse the pussu like I sometimes get carried away doing, its best to give that shit a 48-72 hour rest. But when I come back, its just the same. There's also the women who can control their vaginal muscles and can make it painfully tight if you get in the right position.
I don't know. I have an above average size penis though. Plus I don't really fuck with complete whores that stretch their shit out with giant dildos, so I've never had trouble with a "hot dog in a hallway" type scenario.
However I will say this: in my quest to have sex with every ethnicity of woman I can come across, I have not found a correlation between geological area of descent and tightness of the vag.
