And scholars, from al-GhazalI to al-Munajjid interpret that to mean (as the link describes) that the husband is obligated to ensure his wife is satisfied sexually as she is to satisfy him sexually. What did you think “their need for one another” meant?
“It is narrated from Imām ‘Alī (as): ‘When any of you wants to sleep with his wife, he must not rush her for indeed women have needs (too).’” (Wasāil ash-Shī‘a, vol. 20, pg. 118, no. 25184)
“It is narrated from the Prophet (s): ‘Do not engage in sexual intercourse with your wife like hens; rather, firstly engage in foreplay with your wife and flirt with her and then make love to her.’” (Halliyatul Muttaqīn, pg. 110)
“It is narrated from Imām ‘Alī (as): ‘Whoever wants to get close to his wife must not be hasty, because women before engaging in the act of love making must be engaged in foreplay so that they are ready for making love to.’” (Halliyatul Muttaqīn, pg. 115)
“It is narrated from Imām al-Ridā (as): ‘Do not engage in sexual intercourse unless you engage in foreplay, and play with her a lot and caress her breasts, and if you do this she will be overcome by passion (and excited to the full pitch) and her water will collect. This is so that the emission of the watery juices shoots off from the breasts and passion becomes evident from her face and her eyes and that she desires you in the same way you desire her.’” (Mustadrak al-Wasāil, vol. 2, pg. 545)
“Imām al-Kādhim (as) was asked: ‘Is there a problem if a person kisses the private part of his wife?’ The Imām responded: ‘There is no problem.’” (Niyāzhā wa Rawābith Jinsī was Zanāshuī, pg. 55)
