Why would you shower naked with a bird? Just a little weird but to each their own.
Just part of my morning routine. I had 11 birds at the time, all of whom loved daily baths. The easiest way to do that was to just have shower perches, and when I took my morning shower, so did they. We alternated between birds. So it was about four or five at a time. Then they went back, and I made breakfast for everyone, took my daugher to school, and myself to work.
That way, I had more time on the weekends for "weekend stuff."
So, it was just part of my daily routine... nothing weird about it. My birds loved showers, and it's good for them. The easiest way to do that is if you are in there with them. And who showers with clothes on?!
In over a decade doing that we had ONE incident... ONE... and in retrospect it is kinda funny, now... though at the time it happened NOT SO MUCH!
And as for the other, I surfed for over 25 years. Getting in and out of wetsuits in the parking lot with just a towel wrapped around your waste, and strangers on the beach (some of whom were obviously watching) also fell within my definition of normal...
While I am not an exhibitionist, at some point, you do kind of have to just get over it.
