Fang Yuan stamina

Just translated this:

"Heh... because Shang Zizhu's scrawny and weak—can't satisfy a woman. But Fang Zheng? He's a beast—every thrust uses the Full Effort Gu. A boar's charge, a bear's slap, a crocodile's twist, a horse's gallop, an ox's endurance, a turtle's stamina... which woman wouldn't want that?"

"Ooooh!" Many men nodded with understanding.

Many women crossed their legs, blushing, lost in thought.
