Public places are not pubic places.  The library is a safe sanctuary for individuals—including youth, as the Teen Underground advertises—to research information. The library is not a place for free access to streaming porn on a personal network enabled device—particularly in the case that such depiction shows physical harm, lack of empathy or out-right intent to disturb the typical library citizen.  Beyond these common sense conditions, it is also reasonable to exclude the use of personal device to show loving relationships in the public library place.  Intimacy is a lovely and private interaction in our society. Display of such in a public place suggests an attempt to engage in public display of indirect voyeurism or otherwise non-standard sexual behavior.  Sexuality is not a tool or an emotion to be suppressed, but there are societal norms that need to respected for the good of the common space that the public library represents and the respect of all of its patrons, young or old.
