I’m starting a list of resources for polyamorous vegans. Sadly there isn’t much but I hope to make this list extensive so if you know anymore let me know.
Open/poly vegan fun group (Secret group only adding a few members at a time)
Naughty Vegan Life (Not necessarily poly but deals with open sexuality)
Finding vegan polys on OK Cupid has never been easier with the OkCupid (for the Non-Mainstream User) extension for Google Chrome
VegFet (Membership by invitation only)
I’ll update this list as I discover more links.
