It might just be edging doesn’t do a lot for you. In which case, honestly I’d suggest you just try cumming lots! No point doing it if you aren’t getting some kind of physical or at least emotional kick from it.
But give it a bit longer, see if that changes. But we’re all different and that’s what makes it all so interesting. So it might just be denial ain’t your thing, and that’s totally okay.
Great job on giving it a go though!
