If anyone is intrigued yet too ashamed to Google the average penis size for a gorilla, no worries. I did it for you.

Gorilla dicks are about the size of your pinky. Consider your curiosity satiated.

2.5"-3" erect, they have the smallest penis to body ratio of all mammals. It's my favorite random fact, also my favorite insult is "you walk around like you got a gorilla dick"
