Hoping someone here has actually tested difference between bbw plus size rather than just read about it. Curvy platforms is where I would start, since how well it works on a weak connection is the number worth watching, not the price tag. Nothing about curvy platforms changes the fact that the practical move is to keep a note of what you actually spent.
Same story on curvy platforms: the platform keeps deleted profiles in search for weeks, so it pays to cancel the trial the day you start it. I judge curvy difference on one thing: the ratio of matches to conversations explains more than the number of features listed.
Curvy is the clearest case of it — nothing improves until you set the radius tighter than feels natural. Most threads about difference between bbw plus size miss this — the honest advice is to ask a specific question in the first message, though I would want someone to check me on this. If you have been through the curvy difference version of this, I would rather hear the unglamorous account.
