Slave Narratives

I read the list of Slave Narratives regarding slave holder's sexual abuse on slaves. Everything that I learned while reading this is awful. I'm surprised that some of the women were willing to talk about their experiences and speak up, although they did seem to have a harder time discussing the topic than the men did. It's so incredibly sad that these women had to go through the hardships that they did because if they refused they were punished in a worse way or sometimes killed. Not only did they have to deal with the men, but their wives made it worse. One of the excerpts talks about how the mistress would beat or throw objects the woman that her husband was forcing to submit to him. It's an issue that no person should have to deal with, especially not in fear of their life or further punishment. When giving yourself up to these kind of actions is the better option of being beaten or death, it can't be imagined what these women went through unless you are placed in the situation yourself.

A few of the questions I have.
1. Why do the slave owners get married if they have intentions like these?
2. Why do women marry the men knowing that they are more than likely not going to be loyal to them, and then why don't they leave them?
3. Were there any instances where someone stood up for themselves and fought back or where others fought back for them or with them?
