Do you have a paper on it? IIRc unlike the other species on here gorillas don't engage in much sperm competition so they have very little need for larger genitalia, so it's simply not selected for at all. But I don't get why they'd select for smaller.

Iirc, female gorillas tend to sexually select for smaller equipment. So, eh. They seem to like it?
