That's a good example: Circumcision is common in the US, so US girls tend to like it.Beauty maybe, but sexual attraction is a different matter.
I do not find guys who are overly muscled attractive and I find the penis on an uncircumsized guy much less attractive than a guy who is circumsized.
It is not common in Europe, so girls here tend to like uncircumcised...
That's exactly what I meant with "acquired in the environment".
But there are other factors that are part of attraction as well, for example exoticism...
