I feel like I've seen similar threads like this get taken down, so I wanna preface not to say anyone's name directly (you can heavily imply if youd like). Not sure if that'll help but fuck it.
If you've been with someone 600+ or close to that range, you know just how completely absurd the entire experience in comparison to just regular obese women. The whole mechanics of intimacy, the sheer amount of limitation of movement, just how insanely massive that much weight looks like in person.
Share the experiences you've had, even if its just a date or a chance encounter, and what made it stick out to you compared to others. As much detail as you can ofc.
