I have a rather specific use case for OF. I only subscribe to creators who are providers I’ve seen and plan to see again or providers I’m curious to see, in which case OF can be a sort of due diligence research tool to see if they’re to my liking. For the first group, OF is a fun, non-intrusive, and low effort way to keep in touch and maintain rapport. It can even be used to enhance future sessions (e.g., “please wear that outfit you wore in the pic on such and such date” or “I’d like to try that thing you did in the video posted on such and such date”). Providers/creators I subscribe to tend to be ladies I’m very attracted to and interested in as people and it’s appealing to see them in contexts, states of dress (and undress), and situations (sexual or otherwise) outside of sessions. This builds up anticipation between sessions. OF creators/providers who use it as kind of a life blog leave plenty of things to discuss at future sessions in the ways they document their experiences, travels, hobbies, etc. All these things provide value I find worth paying a small monthly fee for (I do buy vids sometimes but only those under a certain dollar value and I keep to a max monthly OF spend limit).
Caveats: the above only applies to providers/creators who manage their own accounts and chats, not the ones who outsource all that to bots or people in India and the Philippines. Because I have a strong preference for seeing and interacting with these ladies in person vs online and am mindful of the “OF opportunity cost” (for lack of a better term), there’s an upper bound to what I’m willing to spend on OF in money, time, and attention. I’m also currently a single man on a break from dating. The minute that ceases to be the case, my OF consumption will cease to exist. (And needless to say, if I were to ever run into financial trouble, OF would be among the first kinds of discretionary spending to be dropped.)
and that sums up my particular use case for OF.
Edit: perhaps a more succinct way to frame it is that it can be an extension of the GFE and enhances in-person experiences in certain ways.
