I too would really appreciate a "PG" toggle of some sort. I don't really want to see any of that stuff myself, not to mention having to explain things if one of the younger members of the family walk by :P.
Also by having it be a toggle, the people that want it can have it, and those that prefer not having it (I'm honestly surprised at how many I saw in this thread, thought I'd be the only one lol) can skip it.
I agree. I would appreciate this too. Since we have a system of tags, it would surely be pretty straightforward to put a little check box somewhere in Character Creation that would give your character a no-romance tag, so that you would never need to be offended by this sort of nonsense.
