Please teach reading writing and mathematics instead of exposing children to inappropriate material.  It does not matter who or what the "explicit" material involves.  This is not appropriate for the school setting.  My children should not be taught about "explicit" straight or gay sex acts.  Some want to bring up concern that marginalized people might not get there fair representation of explicit sexual activity taught in the classroom, and make it about discrimination.  This is insane, none of it should be in the classroom.  This has nothing to do with representation, it's about inappropriate materials being taught, the right to inform parents, and to let them make a choice on their child's education.
