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.
