So-o-o-o-o-o-o... fetishes, eh?

Now, I understand fetishism, S&M etc. etc.
If you want to be punished, or worship, or be worshipped, or get tied up and beaten, be in control or be under someone's control or dress up and role play, I'm all for it. Yes, this is a very short list.
I find these practices, while being performed between consenting adults (of any multiple), to be a part of a healithy sex life, and no one gets hurt. At least no more than they want.
Fantasy should be indulged, curiosity explored and sexual appetite sated.

However...

I don't understand wanting to pee/shit/puke on a sexual partner (I assume these are not regular practices, and that golden showers [which suggests that these people have unhealthy urine. Urine should be almost entirely clear if you are properly hydrated] are the most common, but I would think that most people would not be very vocal about performing these acts, so perhaps it's more common than I think).
Regardless of the nature of the relationship, whether casual or committed, it just seems like such a strange impulse.
I can associate emotional and physiological reasons for the sexual practices first mentioned, but I see no particular reason one would want to excrete bodily wastes on someone.

Should you perform one of these acts, please don't feel like I'm judging you. I don't understand, but I'm not condenming it.

Anyone know where the impulse comes from?
I'm very curious about it.
