"Ohhhhhhhh~"

"I'm coming"

"Ah-ah-AHHHH!!"

Stop being asses, guys. You know as well as I do that Lyria-chan is using yaoi/shounen-ai as a way of saying the story is about a romance between two men, not that it's just pornography.

( As an aside: sex scenes are like any other scene in a story. They need to develop character and serve a purpose in the plot. They are no easier are harder to write than any other scene in a story. )
