How do I develop these nude photos safely?

My partner and I recently went on vacation where we used some disposable cameras to take pictures. In some of the pictures we're not fully clothed. I don't have to equipment to develop the pictures myself, so I believe the only option I'm left with is to have them developed at a photo center. I don't want anyone to take a picture or keep any of the nude photos we took, but I still want to develop the film. How can I go about developing these pictures where I know the photos won't be mishandled?
