19 years ago? Might be a good idea to let go.
Second of all, the film is probably going to come out completely pink in hue or severely damaged.
I really wouldn't want a bf I had when I was a teenager to be developing nudes of me almost 20 years later.
I hope you at least intend to keep them to yourself and realize that developing photos of someone from your past from when they were underage is maybe not the best idea.
