Thanks for the shout-out (and link to my recent piece), James! :-)
Although I should reiterate that part of the reason why I am nervous/uncomfortable about the prospect of taking my shirt off in public is because of my acne scars, residual acne, and deep stretch marks.
If it wasn't for those factors, and if I just had a plain and unspectacular "dad bod," I'd actually be a lot more comfortable taking off my shirt. But that's just me.
