Despite all of bernard talk of being unhappy with the present conditions of society what does lenina ultimately think is bernards reason for not wanting to go to bed with her

Bernard truly does not want to go to bed with her as he is constantly troubled by the state of the world, and he does not want to only hook up with someone and have a one night stand. He wants something more meaningful but Lenina does not understand this. She fully believes that he does not want to sleep with her because she is unattractive to him and not good enough.

In "Brave New World," Bernard does not want to have sex with Lenina at first, as he wants something deeper, something more than just a physical joining. Lenina does not understand his philosophy, however. They do end up having sex, and Bernard regrets it, and he voices that regret. To Lenina, his regret was not reflective of his remorse for having abandoned his desire to grow intellectually, but because he found her unattractive, undesirable.
