Is the game bugged or its just some scenes have space for images/gifs but there are none? The fastest one I can see that that happens is going to the second floor of Mark-Us Sex shop.
If I “inspect element“ I can see that there is a “<center></center>“ where an image/gif should be, but its empty.
(edit: going as a Sub Guy gives me enough Social and pervesion for the scene to be narrated and be able to choose both oral and anal sex)
