One, having a slit or dick on a page doesn't automatically preclude something from being interesting. You're an adult, you don't have to sperg out at the concept of sex.

Two, it takes time and effort to translate and market something truly interesting. You have to have an understanding of a work and the visuals that carry it for something to really stick with you. This is naturally impeded by both the time a normal person has to spend and the time it takes for something to cross the language barrier.

Three, cool things are cool, pretty things are pretty, tits are life, ass is hometown. You'll find that universal, simple things, are always popular and tend to cross cultural bounds.

Four, you already knew the answer to your question before you posed it. The only question we have left is why you still asked it.
