Ahh yes, water sports. Fundamentally different when it is solo play / own urine or partner play / partner's urine!
Dom or sub? *coughs* you mean top or bottom ;P I switch, and yeah I can absolutely see myself in the dominant-bottom quadrant as well.
I have listed under my likes, but this is more of a higher tier of play to me.
What I mean by that is pee play for me is less about the pee it self but a symbol of trust, familiarity, connectedness. I find other people's pee utterly disgusting and my own embarrassing up to the point where I have built something with them, after some (much) time there comes a point where I feel safe enough with them to let it out / on. This is all somewhat hypothetical as I only ever had a single person get that far with me. I found the entire experience extremely empowering, akin to being tied up as the model for a shibari workshop, being looked at for reference.
Now when it comes to solo play or my own pee, it's going straight into wet and messy and I love to feel it on my body. I am usually very sensitive to smell so that is a factor, and therefore I prefer clearer pee over darker one. I also drank it out of curiosity, but that did absolutely nothing for (or against) me. It's just gone and cannot be played with anymore (booo!)
Now wetting myself.. In the shower/bathtub that happens from time to time but I think this is more about wetting while clothed? I did try diapers not that long ago, if that counts. I can't recall when was the last time I wetted myself in regular cloths though.
