Is it permissible to educate a young man about to get married on matters of sex through a detailed Western book with illustrations, to avoid embarrassment and benefit from the detailed explanation?

It is not true that the Prophet, peace and blessings be upon him, ordered the teaching of sexual matters related to the wedding night to young people. There is no harm in teaching the etiquettes of sexual intercourse as prescribed by the Sharia. It is not permissible to give a young man a book containing pictures of private parts or depicting impermissible forms of enjoyment. Books of Islamic jurisprudence suffice over such books.
