Hello, thank you for checking the game and for taking interest in it ;)
- Sadly there is only vaginal at the moment. There are anal plugs however, in mouth items (changing character's voice lines) and other features (can be checked in game description, also please check the Updates from 1.1 up to latest for the added features).
I will think about adding anal, however that won't be implemented in the upcoming updates.
I hope this helps,
