It would be worth it to be spared one more drearily repetitive Daddy/Dee shower scene
This is technically spoilers, but so far, there aren't any FmF daddy/daughter shower scenes. Maybe in the epilogue/endgame after all is said and done, 'cuz it's gonna happen sometime, but FmF is leading up to one big day, where everything happens. I.E. by the end of the big day, unless F is a complete moron, F ends up having sex with someone...
Now that's NOT to say that there won't be any water scenes. There's a possible swimming pool scene, and Dee does take a shower at some point, maybe not with F though (I can neither confirm or deny...).
Of course, the big day is after a couple of months of 'prequel' stuff (dreaming about Deebarella, Ron and Rachael getting it on with those teenagers, etc.), but Dee doesn't meet F until the 'Big Day'.
