Yes, absolutely. The state law requires, in several different places, that your child's sex education prioritize and emphasize abstinence. 

It must:

• Teach "abstinence from sexual activity outside of marriage" as the "expected standard for all school-age children" (§ 115C‑81.30. [a][1]),
• Teach "that a mutually faithful monogamous heterosexual relation in the context of marriage is the best lifelong means of avoiding sexually transmitted diseases" (§ 115C‑81.30. [a][5]),
