Differences in vaginal tightness according to ethnic origin?

Sometimes people claim there are differences in penis sizes according to ethnic origin. Are there differences in vaginal tightness, or other genital conformation?

Based on my own experience I have never believed that penis or vaginal size has anything to do with ethnic origin. Penis and Vagina’s come in all shapes and sizes. I believe it’s in your DNA code that you had the day you were born.

I sincerely doubt it. Genitalia comes in a multitude of variations set in place by the DNA you inherit.

It's worth noting that in my experience, smaller man does not equal smaller penis. (And a perfectly average penis on a very large man can look pretty small!) I presume similar outcome from smaller women and their vaginas.

I think the stereotypes are not accurate. I’ve seen plenty of women claim “Asian men have small penises” yet one of the largest penises I’ve ever seen was a guy from Japan, or “African guys have huge dicks”, yet I’ve seen plenty on r/sph among other locations…

When it comes to breast sizes, there may be a correlation of Asian women having smaller breasts than Caucasian women for example, but I am not convinced that it is because of genetics alone, but culture in general. Compare the stereotypical American’s diet & exercise habits to those of a Thai or Cambodian person…

When it comes down to it - the penis and the vagina are muscles. How often are they used? How are they worked out? It impacts the look and feel. But also, it’s very individualistic.
