I agree that this varies from relationship to relationship.
At my job we have a saying, “Never put anything in an email that you wouldn’t want to see as an exhibit in a legal proceeding.” I feel confident that I could engage in roleplaying with an anonymous Size acquaintance without forming an improper emotional attachment, but I wouldn’t want to have to defend the transcript to my partner.
I’m much more comfortable keeping to my current practice of writing stories with one or more Size acquaintances in mind and hoping they eventually figure it out. 
@Kondo Try telling a Borrower chick she can’t survive on her own. Then try to find your car keys.
Fingering her as she shrinks until she’s stuck snug on the tip of my pinky.
@foreverlurk I’m sure Banks appreciates a set with functioning plumbing rather than a chamber pot.
@littlest-lily Yup, I do the “quick sensation” daydream too. Usually just looking at my open hand, then curling my fingers and imagining how she feels against my palm. Just a few seconds away from reality.
@The-Big-G I don’t recruit among my irl acquaintances because I couldn’t trust myself not to say something creepy. I don’t do it in a F/m context, and I sure as hell wouldn’t do it in a M/f context.

Though about the one where I am dangling from one leg, I do like the position very much, but I don’t like to be held in that position for too long, my blood needs to go back to my body.
Don’t worry, it’s only funny for about half a minute.
(Until the next time.)

I will add that we have to consider the broader socio-cultural context in which content is produced and consumed.
The OP was singling out F/m for the particular harms it can cause. The (straight) male gaze problem is present in all media and genres, and M/f is no exception.
@maladaptivetiny I never know if any of you are carrying diseases.
