If you are both adults and the photos are not obscene, then there is nothing prohibiting the photos. Obscene is determined by community values and I am not licensed in IA. However, once they are sent, the recipient can do anything with them. This is how scandals start. Also, think about what a future employer or significant other would think if tha person saw these photos online.
