Well you are not dumb. I should have been more explicit. As sapiosexual, main attraction from a partner is intelligence and mental stimulation. Then practicing golden shower the way i described it, would be for me mindblowing not because of physical degradation but because of what your partner is willing to do: to be submissive just for you and accept such a thing. We are sharing most taboo fantasy in this post, so for me that's what it is all about.
I think I know what you mean by sapiosexual to lead into golden.
It seems a little like what Master talks with me about. Often many subs are actually lifestyle alpha, and need to de-stress by going submissive, rather than carrying the weight of the world while they are sub. I know there is an extra twinge of excitement for him to have someone he looks up to as a person, be willing to take such a submissive role to him. The higher someone's solo power, the hotter the mental turn-on that they gave you the power to lead them, and happily accept that level of submission.
It helps to hear it worded as you do, as golden is something I still scratch my head at, and can't fathom how anyone could like it. (Logically it makes no sense to me, but there is little logic in pleasure and desire sometimes) Though is something I know full well I will be doing with Master at some point. I'm just kind of happy it hasn't been yet, but he wants me to be on board and ready to accept with the right mindset when we do.
Even how he words it, it isn't just a simple act. There is a whole mental mindset behind it that just peeing on anyone isn't it, but the personal connection, and bonding between the 2 while enjoying the dynamic beyond the act. It becomes a mental situation, over a physical humiliation.
