Everyone does poly a little differently. For me, a small number of emotionally intimate, affectionate, stable relationships are what gets my serotonin going.
I'm currently seeing ladysatyr, sempivirens and susanstohelit. So, close to polysaturated, but I can make time for someone awesome.
I find the right kind of intelligence arousing. Not just interesting or desirable, but shallow-breathing, deep-passionate-kiss-inducing arousing. Some men are into redheads or big boobs; I'm into brilliant women with stunning vocabularies.
I'm into ethical erotic hypnosis: Using trance in kink scenes. Trance itself is pleasant, like a gentle subspace, and it lets us create sensations and experiences that your unconscious mind thinks would be fun. I organize the Wicked Grounds hypnosis munch, taught a class while consulting in Melbourne, Australia, and help organize hypno-kink parties in the bay area.
I'm also open to most activities that don't involve pain for me.
I took two years off between tech jobs to teach west coast swing, and I still go dancing every week or so. If you're a dancer (or want to be), hit me up.
I specifically picked an apartment near an indoor gym so I'll get exercise. And I recently started climbing weekly with a buddy. At the moment, 5.9 is comfortable, 5.10a is hard.
Professional bank robber. International, even.
(I'm in security consulting. If you want to know how cross-site request forgery or sql injection work, I'm your man.)
Science and Technology
I'm much more up on new startups and tech news than I am on politics. If you think the asteroid mining company is awesome, we might just get along.
