photos of sexually explicit encounters

strictly speaking it's the photos or videos that are "sexually explicit" - that's the source of troubles.

no one would make any fuss about photos or videos, whatever they are about if the photos or videos themselves are not "sexually explicit".

"Sometimes, the photos or videos of sexually explicit encounters make the rounds immediately, even while the couple is still on good terms."

should be

"Sometimes, sexually explicit photos or videos of [sexual] encounters make the rounds immediately, even while the couple is still on good terms."

or even better:

"Sometimes, sexually explicit photos or videos of their [the couple's] encounters make the rounds immediately, even while the couple is still on good terms."

IOW you have the "encounters" and the related "photos and videos" but the adjective "sexually explicit" was coined to qualify "photos and videos" not the "encounters".
