No nudity.
Joan's jailkeeper looks at her lustfully, and at one point tries to rape her.
There are women in the first scene with Joan and her troops. They are referred to as "camp followers", which is a euphemism for prostitutes. But we never even see them flirting with the soldiers, much less having sex with them.
When her soldiers take leave of her for the last time, there is an extremely subtle, unspoken hint, immediately sensed by Joan, that Jean, Duke of Alencon, is platonically in love with her. She leaves him quickly, since the idea of falling in love and having a romantic relationship would conflict with her mission to save France.
