Sounds like you’re on a pretty normal development arc. For a lot of the girls here, this all started as a sexual thing, but then progressed into something else. For some it will only ever be about the sexual excitement, and if that’s you’re thing, there’s nothing wrong with that. Many girls however move past that to find that dressing is more mentally and emotionally gratifying than sexual. Just two different paths. The next thing you can probably expect is a drive to perfect your presentation and a desire to be out in public, or at least be dressed around other people.
