I think there's a lot of people screaming based on fear of missing out or the need to unlock every scene like a collector or they're achievements you need to score.
And that's the wrong attitude.
The game is very upfront about every option, far more than real life so if to don't want to date a stripper you don't have to. You can say no, as far as I know, pretty much every girl who's doing that you know about right off. You might bang them and move on at worst without putting a choker on it and claiming it worst case. Moreover if you have a look but don't touch attitude you can tell them not to do VIP dances aside from maybe 2 who already were doing them before you started up with them - so you knew what you were getting into. I mean fuck Nikki was the main stripper and turned out to be a virgin which has probably never happened ever in that line of work but bless that girl she's amazing. I wanna put babies in her so hopefully we can fix that with pelvic biker magic super sperm.
And regarding Della you have the clear option FOR HER TO NEVER EVEN OFFER anything physical preempting your need to even refuse her if you are at all concerned about cucking Stan the Man. Or just don't like older women. Either is a very good reason, and that is there for you. So there should be no concern or need to fret about it unless the idea that some other person reason the same story as you may choose another option.
But fuck that, just play your story, and be happy its a really good story you can make your own. You are not missing out by having standards on who you want to be with. Hell, I wish more men had standards in the dating market to reign in the simp economy. You don't need to say yes to every possible offer iut of desperation. Pick your favorite fantasy hotties or collect them all, but don't bitch about it.
