Jimmy speaks the truth. 4 wives however is very rare. Even very wealthy men tend to stick with 2. One wife for more connections, kids and an heir. Second one is just a younger trophy wife.
What's more common though is that a man might "marry" a woman for a day just to fuck her and then they divorce. These women are basically prostitutes.
Rape isn't exactly legal, but a married man can pretty much rape his wife without repercussions. Also if a woman finds herself alone with a man and she gets raped then she is just at as much fault as the rapist. Even if she takes it to court, she will fail because the man can deny it was rape. A mans word carries twice the weight of a womans.
It's not all roses though. Your friend Jimmy denouncing islam is an executable offence. It's the duty of any muslim to kill him on sight for this blasphemy.
Not in most muslims countries anymore. Courts are standing by the women in most cases. Men are suffering worldwide now.
Islam say that a woman should fulfill her man sexual needs and that the man should take care of her and his family. It's exactly like the traditional families 100 years ago all over the world. The woman stay home and take care of it, the man must work outside and support his family.
The marital rape is a big bullshit. It's not like she gonna suffer psychologically or even physically by sleeping with a man she slept with thousands of times. It doesn't have an impact on how she gonna proceed in life afterward. That stuff was made up to make people not get married, just as they did with feminism movement. They never loved women or wanted their own good.
As for multiples wifes and concubines that's a fact in Islam. You can have 4 wifes and as much prostitutes ( There's more here
https://en.wikipedia.org/wiki/Jarya) you want in your home but they put rules about it too and it's mostly for people with Harems, like today mansions. Floyd Mayweather and Dan Bilzerian are doing just the same now.
Islam and all historical movements before feminism gave men plenty of freedom, rights and power. It's all gone now.
