This question and the whole etiquette of marriage, what is permitted, allowed, and impermissible is nicely explained in the following books: Marriage and Morals in Islam by Sayyid Muhammad Rizvi: https://www.al-islam.org/marriage-and-morals-islam-sayyid-muhammad-rizvi/chapter-three-islamic-sexual-morality-2-its
I also suggest to browse the category if Marriage of Al-Islam.org to find more useful texts and lectures on the subject: https://www.al-islam.org/library/marriage
