Was Muhammad a womaniser? Absolutely, many Muslim men acknowledge that. Was he a corrupted politician and writing the Quran himself? Let’s see.
Muhammad was supposedly a humble messenger of Allah. To follow everything Allah told Him to do. But when Allah said maximum of four wives, Muhammad had at the time of this story 9 wives, many concubines, and still to Aisha shock, Muhammad was sleeping with any Muslima who came along, even without the approval of a guardian. So Ausha kick up a fuss with Muhammad, like what the hell!! But next day “Allah” responded with an out of jail card:
‘…and a believing woman if she gives herself to the Prophet [and] if the Prophet wishes to marry her; [this is] only for you, not the believers. We certainly know what We have made obligatory upon them concerning their wives and those their right hands possess (women sex slaves), [but this is for you] in order that there will be upon you no discomfort. And ever is Allah Forgiving and Merciful.” Quran 33:50
Subhan-no-Allah. Can you guess what Aisha response was? “
‘A’isha (Allah be pleased with her) reported:
I felt jealous of the women who offered themselves to Allah’s Messenger (ﷺ) and said: Then when Allah, the Exalted and Glorious, revealed this:” You may defer any one of them you wish, and take to yourself any you wish; and if you desire any you have set aside (no sin is chargeable to you)” (xxxiii. 51), I (‘A’isha.) said: It seems to me that your Lord hastens to satisfy your desire.

Sahih al-Bukhari 4788
And why is this a problem? Because in multiple verses Allah says to follow the example of Muhammad in everything:
“Indeed, in the Messenger of Allah you have an excellent example for whoever has hope in Allah and the Last Day, and remembers Allah often.” Quran 33:21
But is he an example? Before his death, he had married a total of 13 women, 9 were still alive or with him at the time of death. This is the same person who dedicated a whole chapter (4) to honour women, but when you read it, it is mostly about how to control women and have sex with them! Go read it.
