In David and Jonathan, Voigt has written a sophisticated book that deals with weighty problems. In such a book it is inevitable that there will be potentially sensitive areas. Topics which may be of interest to parents, teachers, and librarians: 1) The book includes a discussion of masturbation. 2) Henry has homoerotic and heteroerotic fantasies.

3) Jonathan's sister Enid and David have a sexual relationship which David discusses with Henry. 4) Vulgarities and curses are occasionally used. 5) There is frequent discussion of religion, including an instance in which the genitalia of God is mentioned.
