There was a hushed discussion in Eren's dorm room. Not that Eren knew of course, as he was outside. Titans had genitals. Or at least they started to. The last few waves of titans had sported them, but there didn't seem to be any difference between these and the ones before. "Ummm… It's a bit awkward trying to kill them." Armin nervously started, as the topic had never really been discussed before. "I know… I mean, I don't want to look, but…"
"They're really big." Mikasa mumbled.
"They could probably crush you to death." Sasha muttered.
"They probably can." Levi agreed.
"That'd be a bad way to go." Mikasa muttered glibly.
"Yeah. Pretty humiliating." Reiner agreed.
"I don't want to think about it." Sasha whispered.
"Nobody does."
"You could get stuck in there." Levi said, not dwelling on what he said. The others did.
"OH SHIT. DON'T MAKE ME THINK ABOUT IT."
"WHY ARE YOU PUTTING THIS IN MY HEAD LEVI."
"I wonder if they're like human ones. Like... pissing and the other things." Armin whispered.
"JACKING OFF. JUST SAY IT ARMIN WE KNOW WHAT YOU MEAN." Jean said loudly.
"You'd drown in that."
"Even worse way to go."
"Do they have needs then?"
"Probably. I don't want to think about that too much."
"What if you chop it off?"
"They'd probably regenerate it."
"Why are we even talking about this?"
"Do titan shifters have them?" Reiner and Bertholdt shared an awkward glance, then looked down.
"I hope not. I mean, it'd be awkward for Eren to go titan and it just be dangling there."
"I wonder if it'd be smaller than the rest of the titans."
"The Colossal Titan would have a massive skinless one." Bertholdt's eyes widened, taking a long, meaningful glance at his manhood.
"I don't want to think about that." he muttered. "The Armoured titan probably has an armoured one." Reiner's idle voice sounded.
"Would the cold make it shrink?"
"I don't know. Maybe if Eren goes into Titan form in the winter we can check."
"You want to look?"
"Do titans have sex then?"
"Why the fuck are you talking about this?" Eren asked, walking through the door.
"Oh! Eren! Become a titan and check in your manhood's there." Mikasa asked quickly.
"You'd like to see his manhood, wouldn't you?" A voice drifted over.
"They're like brother and sister, that's fucking incest." Connie said.
"But not quite, they're not related. But sort of I guess."
"Okay. I'm going to go outside and come back when there's less weird shit going on."
However, not a minute after Eren left, they heard his distinct roar, and then silence. Then the unmistakeable sound of him returning to human form, and he walked back in. "Yes, it's there." Eren sounded relieved. Reiner and Bertholdt looked down for the third time that night, as Eren sat down on the end of his bed. "Hey, do you think female titans have nipples then? And, umm… THERE?" Eren asked.
"VAGINA. EREN YOU CAN SAY IT." Annie, who'd been silent for a long time, near-shouted.
"Does that mean titans can breast-feed?" Eren asked to nobody in particular. Annie, like the other two unrevealed titan shifters, stared down at the parts discussed. "Can titans get pregnant?" Following that, there was a loud banging at the door.
"THAT'S ENOUGH WEIRD SHIT FOR ONE NIGHT."
