Yes

Eager to learn more, Aloy excitedly asks what sex is.

Rost takes her by the hand, and leads her back towards the house.

“Sex is two things.” Rost spoke, as he guided Aloy back to their home. “One, it is how humans procreate and have children. Secondly, and most importantly, sex is about pleasure and fun.”

Aloy looked up at Rost, and saw a odd hunger in his eye she had never seen before.

“Are you going to show me how sex works?” Aloy asked, knowing Rost often taught by example.

“Yes” came the reply. Reaching the house, they went inside and Rost closed the door behind them.

“How do we begin?” Asked Aloy, taking everything seriously as usual.

Rost looked at her, and once again Aloy could see the hunger in his eyes.

“Take your clothes off” Rost said, as he began to disrobe.
