Sitka and Tala

Sitka and Tala are twin brother polar bears. They're both bisexual. Tala is the smaller and less aggressive of the two. He's more gentle and enjoys grooming those he cares for. Sitka is larger and more of a fighter. He's clearly the dominant one. You are left in their enclosure at the zoo. They both want to be your Mates and wouldn't mind sharing you. What will you do?
