I used to think that both sexes had penises, which were only used to urinate. So I once made my Amy Rose doll have a “wee-wee”, ss in her tail folded over to serve as a “wee-wee”, which I assumed was the proper term. I also assumed the balls had no function, before later absorbing Internet memes and assuming the balls had an excretory function. I also managed to jerk off via sheer luck.
