I found Arrange Marriage is Weird

My cousin recently got married. He grew up in a village and then relocated to Dhaka for job. His family found a lady for him, and he simply accepted her after seeing her for the first time. I encouraged him to speak with that lady, so I set up a meeting for them at a restaurant, where the lady arrived with her brother. I was having a pleasant talk with her brother when I noticed them both sitting at a stop. They were too shy to talk, and the lady said nothing except yes and no. After only two weeks, both families had planned the wedding. Before going to bed, all of his friends and other companions were encouraging him to. The next day he was bragging about his experience of having sex. He even said this morning his wife is too uncomfortable to even make eye contact with him. I found this entire situation super weird from the lady's POV. She came to know my cousin just two weeks ago, and now she's having sex with him. She has no room to say "no." . Why our culture and society doesn't provide a single space for a woman's sexual preference?

Note : I have posted the same topic at r/Dhaka and the feedbacks made me depressed. It's concerning that most of them normalised this act. Post Link
