Ugh, I agree so much. Fingersmith is probably one of my favourite films ever. Tipping the Velvet is even better, ca you believe there was an uproar against the too much lesbian scenes? Ermm.. duh.
But FS is closer to my heart. I love the twists.
Sommersturm might be one of the best coming of age, realizing, coming out movies out there. It was sensitive and smart. And handles the issue without too many clichés but it's still fun.

And the erotic scene is one of the most beautiful one in film, it's innocent yet arousing and...very very hot.
Let me recommend a Hungarian movie: Egymásra nézve (Another Way) from 1982.
It's very good and tragic but never sappy. I was completely overwhelmed by the rawness of Makk's storytelling.
Ermm, one last thing. I don't know if I count Persona as a gay-themed. It's much more complicated than that. I have actually written a paper on it for my film class, as it is my favourite film ever.

I love it so much. Liv Ullmann is the most perfect specimen that ever graced our world. But this is a whole different topic.
