The random masturbation scenes and the girls fooling around with each other are mainly there because it's still a sex game, and when you have gone x amount of time without anything hot it's there to be all "heeeey buddeh heres a lil somethinsomethin." to keep people interested.
I like that you can pretty much shut down a good deal of the side quest crap when you're wanting to tunnel your daughter's relationship and nothing else. But honestly it sounds like all it would take to make those who don't want the extra nonstory related smut in the way of what they are doing happy is to just have a skip scene button on content that's completely unrelated. In some cases it could be interesting too (even though the example is story related). Imagine getting the text of el from jen out of nowhere without knowing it's coming just completely out of context. That would add some great immersion, and would motivate people to replay with intent to focus on side content.
