Left leaning engineer, working to better the world, seeks full time or part time partner(s).

I've had a couple of BDSM based relationships, but nothing too heavy.

I'm looking for the holy grail, a long-term relationship. I suppose the chances of finding one on here are vanishingly rare. However, I'll just put that out there.

In the meantime, or maybe as a starting point, play partner(s) would be most welcome.

I am pretty practical when I put my mind to it. I'm creative, too, with inventions, books and lots of photographic experience.
