The EBU is the umbrella association of national Buddhist unions and Buddhist organisations in Europe. They also have a Rainbow Sangha with the aim to connect Buddhist LGBTIQ+ groups and teachers worldwide. So if you are interested, have a look at the site to see how we can all help each other.
They are currently conducting a survey to see what opinions/views there are on this topic within Buddhist circles. So please take part, also if you are cis.
