What is the ruling on browsing pornographic websites online that contain important information, without looking at the pictures, and what is the ruling on reading books that discuss the topic of sex, such as "The Perfumed Garden"?

There is no harm in browsing and viewing cultural sexual websites between spouses if there is a need for them, and if they are free of prohibited images and obscene language. As for the book "The Perfumed Garden" by Al-Nafzawi, it is not recommended to read it due to its explicit and scandalous style, obscene language, and stories that violate decency.
