"Ok."
"You know what makes men different from women, right?"
Rapunzel nodded. "They have beards and lower voices."
Eugene's face was very red at this point. "True, but, um, did Gothel ever teach you about the nether regions?"
"I've never heard of that region before."
"Oh God." Eugene shook his head. "Look, you know the, uh, place between your… legs?" He seriously wanted to run and hide at the moment. Sexual education was not his strong point.
Rapunzel blushed. "Yes?"
"Well, the place between a man's legs is different than a woman's. And they fit together."
"Really? That's interesting."
"Yes. And that's how pregnancy happens."
"Really?"
"And… it feels quite good, actually."
"Oh."
"And you're really not supposed to do it until you're married."
"Oh."
"So that's why your parents won't let us sleep in the same room."
