Getting involved in your local kink community is a way to meet other folk who are at least broad minded and accepting sexually. Now I'm well aware that many 'kinky' folk might still be very judgy about zoo but, from my experience so far, many are at least willing to listen, think it through and then, sometimes, respond with (eventually), 'you know, that sounds kinda hot'. It takes A LOT of trust but so far, on the four occasions I've opened up to someone, I've had two 'interesting, but not for me' and two 'kinda hot' with one becoming a very fulfilling long term relationship.
This is VERY dependent on where you are, though, and everyone needs to judge personal risks very carefully and protect themselves.
