I think we all know what golden showers are, having your partner piss on you, or them wanting you to piss on them. There are different types of watersports. Some do like the pissing on, others are just as aroused by seeing others urinate or some even like to see others wet their clothes. Seeing a growing wet spot through your clothes drives some men wild.
One client I speak to is always interested in any “accidents” I ever had, and wants to hear about them in detail. Some in the BDSM scene like to make others get a very full bladder as a type of uncomfortable punishment. To make the other person beg to be allowed to go pee. I’m sure many of us know that when we get a full bladder it can make you feel temporarily horny until you relieve yourself, or if you’ve ever had an orgasm with a full bladder it can feel fantastic, but if you wish to avoid an “accident” it’s best not to do that.
Some love the sense of humiliation of being peed on, others love the control and sense of domination over the one they are peeing on. I’ve often thought the roots of such a fetish must go back to early childhood, since many people’s first discovering their genitals would have come about during toilet training, and somehow they got mixed up together, the memories of urinating and touching yourself and them coming from the same spots creates something in their minds that binds the two together, so forever more they are sexually aroused by the act of urinating.
