back in 1990 I lived in Florida and did some marine construction. We worked doing seawall repairs on the intercoastal. During the months of Jan and Feb we wore wetsuits.
When nature called (#1) we just peed in the wetsuit. It does warm you up but takes getting used to; letting the flow start.
Cleaning the wetsuit is essential. Urine leaves the body almost sterile but will leave a rash.
#2 is totally out of the question.
