The legal definition of "sexually explicit content":

(i) any description of or (ii) any picture, photograph, drawing, motion picture film, digital image or similar visual representation depicting sexual bestiality, a lewd exhibition of nudity, as nudity is defined in § 18.2-390, sexual excitement, sexual conduct or sadomasochistic abuse, as also defined in § 18.2-390, coprophilia, urophilia, or fetishism.

I do not understand how in any context would a teacher come across this problem while instructing children. This bill is unnecessary, and it makes it much easier for a bigoted parent to censor the education of children attending public school simply because they did not personally like the curriculum.
