Now, I don't want to alarm you, but it sounds like you have a rather unique situation if you must unfold your naval, and that it smells after 6 hours from washing it.
My naval! I'm very thorough when showering - I absolutely hate feeling dirty. But I think the ol' belly button gets overlooked because of how concave it is.
Isn't this meme the definition of the egg experience though? Not to tell anyone how to live their lives, but this feels pretty textbook for trans-person-in-denial.
I forgot to mention The Exploring Series in my answer! Glad you mentioned it!
