Well, the Leyla scene Planetwendal mentioned isn't really avoidable, this one you'd have to click through with half-closed eyes or something, I'm afraid.
If you can wait a bit, I'll cook up an alternative to make this part of the scene optional in the next update.
The first Kate dream is femdom, too. The dream is avoidable, but going through it once is required to unlock the dungeon.
All other femdom is purely sandbox and therefore avoidable (not that there's much of it).
