Honestly...watching a woman cum. I don't find it erotic watching a woman pee.
Touching turns me on and a great smelling man. Makes me real wet. And a deep voice.
Of those two choices, the climax. Seeing a woman in the throes of ecstasy is hot. I love watching women masturbate for precisely this reason and it probably explains some of the appeal of girl-on-girl porn.
Urination is not my kink.
Dont know why so many men want to watch a woman pee? Many have asked me to let them watch and I've done it for the odd special few. That seems to turn them on like nothing else - and certainly more than watching me make myself orgasm.
Oh that is an easy one for me... when a woman orgasms. Watching a woman pee is... "That is nice, mmmm", but watching a woman orgasm is ...."Fuck!"
Having my man touch my spots that get to mmmmm.
The switch. I'm not talking about the BDSM type switch, no way. I'm talking about an actual DPDT (Double Pole, Double Throw) electrical/electronic switch, deeply embedded in my power circuitry.
making a women cum hard is a turn on for me. the peeing thing not so much
