The owner of the group got notice from immigration that for extension purposes, foreign women married to Thai man will remain the only ones who do not have to show financial proof. All other marriages will require proof of funds. Thai male foreign male, thai female foreign female, Thai female foreign male.
I've yet to hear of anyone getting a visa or extension within Thailand based on same sex marriage, but based on the immigration policy, I would not expect there to be any preference to any other marriage type except Thai man with foreign woman
