>>12145084shit and piss feels so good because there is an evolutionary benefit.
The benefit is that it also feels good to dock (penis in penis) and to have anal sex, which promotes male comradery, which allows men to work together and keep their tribe together.
The evolutionary benefit of keeping the tribe together is that you can have children and raise them to adulthood.
Evolution therefore selected for:
Raising children to childhood > a safe tribe > brotherly comradery > anal sex and docking > piss and shit feels good
