I know what you mean. Not animations but it's kinda weird that when you pick futa it's just like it is attached to them to stick out. I mean, they are in clothes and it looks funny like it was glued to their pants. It needs some changes if skin has clothes or don't. If not then it's fine, if yes then add bulge on clothes and penis can stick out straight up not straight.
Also color change when skin is changed. Golden Bonfie looks funny with purple dick but you know, it's not how it's supposed to be.
