Swan Lake is a hetero tragic(though some versions have happy ending) romantic epic composed by a homo.

IMO he did an image transfiguration:

Odette was a princess trapped in the body of a swan waiting for prince Siegfried to rescue and mount her <==>

Tschaikovsky was a homo trapped in a hetero world waiting for prince Sickfreak to rescue and mount him.

(I once gave the video to a hyper-sensitive but rude female and jokingly said 'don't watch it if you just had a failed love affair because you might commit sucide jumping into a lake like Odette did.')
