I like people who are warm and connecting, creative, have a love of life and ideas. Really, someone who I feel connects on as many levels as possible. In terms of quirks, I don't mind anything silly or strange, as long as they don't feel like a liability.
Turn ons include: dark hair with green eyes ; a humanistic side, like I love it when someone seeks to change and improve things; outgoing and adventurous, I like the feeling that things might suddenly become more wild; intelligent, I like to be challenged; philosophical and self-analytical, ie. the ability to keep learning and improving; loving, affectionate, engaging, open, all the normal stuff.
Turn offs and deal breakers: I'm actually pretty accepting, but if they clip my wings or anyone elses as a matter of practice, are arrogant and dismissive, inflexible and all about themselves, look like there is zero chance that they will form anything mutual and connecting, I am normally on the way out.
In general, I think we like to not set rules though. So anything that comes up in the thread will probably have exceptions and change given the context. I'm always on the lookout for the things I didn't know I wanted as well.
