You can write the most detailed, vivid description of an ax entering a skull, and nobody will say a word in protest. But if you write a similarly detailed description of a penis entering a vagina, you get letters from people saying they'll never read you again. What the hell? Penises entering vaginas bring a lot more joy into the world than axes entering skulls.
