Like pls, I just want to satisfy my suspicion that elf sexual relations can be characterised by the heteropessimism form (already have proof/substantiation of that for Numenor) or to have it definitively debunked by actually engaging w the gender relations as they exist textually

There is an astonishingly high amount of actual/attempted male control over women in the Silm and also a lot of textually broken up elf/elf marriages! The most successful ones are either interspecies or peredhel/elf or peredhel/peredhel w the notable exception being Galadriel & Celeborn
