Coworker [F] saw a nude picture of mine [M]

I have a coworker (let’s call her Marie) with whom i get along very well. We travelled together for several weeks for training and we became good friends rather quickly. It was never flirty, just two people that hit it off very well. We enjoyed going to the beach together in the free time of our training and having a glass. She is of arabic origin, with dark hair with shoulder length, dark eyes, and a very very voluptuous body. But what I like the most about her is her smile, which illuminates her eyes.
