Clothes are natural, people always clothed themselves....they didn't always use contraceptives. You need clothes as protection against the elements. Creating new life comes from natural sex, and sure, contraceptives can protect from STIs and HIV and herpes, but taking care of your genitals protects against those things as well.
You and I are in reverse on the whites/Latinas thing, I've knocked down a ton of white women, only three Latinas. Small sample size but I wouldn't say I have the impression they are better at sex than black women.
I don't think any race of women are better at sex than black women.
White women generally can't fukk, you find one here or there who can, but they generally aren't equipped for The Mandingo. I do like their eagerness in wanting it, though, which isn't really different from the eagerness of other women, I just think because white women are so culturally and personality different, its a specific turn on for me.
The best three I ever had? I don't know if this is in order but this one chick, when i was 16, she was 18, brown skin fat chick. To this day, the best head I ever had, some of the best p*ssy I ever had, that shyt was fukking amazing.
When I was 24 I was smashing this 18-year old brown skin chick, head not much but got damn the p*ssy was incredible. One thing she had in common with the other 18-year old, just really sexually experienced for her age.
And my youngest daughter's mom, who is "technically" Afro-Latina (her dad is from DR and looks like Ice-T), just amazing p*ssy.
There's about 6 more I can think of that are up there, combination of great p*ssy and sexual talent.
To the bolded, 

. A true rider can ride anything if it ain't no micropenis 

 but you on point that most women also don't have great core and leg strength, I never considered that but its true! And you may ne on to something about the gym rats being able to ride better, I gotta test it out.
I will say that if a guy got length that make it harder for women to ride who aren't pros, they tell you it hurts, can barely move, etc.
You need more p*ssy. 90% of vaginas does NOT feel the same
