Feeling lust after unintentionally looking at one's sons private part

Q: If a woman unintentionally (accidentally) looks at the private part of her adult son without clothes by mistake and she lowers her gaze, but due to looking at the private part without clothes she feels lust inside and she feels some discharge coming out of her private part. Even though she does not have any lust for her son and she lowered her gaze as well, will it constitute hurmat musaharat?

Giving food away that one would not eat oneself

Q: I am a student who went home for lockdown. My electricity had tripped approximately 15 hours prior to my return. My freezer stuff was not frozen, however it was room temperature and I now have doubts whether I can give it away to someone else as I am not sure if its okay for consumption. I know it is sinful and wasteful to throw away food and it is also sinful to give away food that you would not eat yourself. What do I do?

Woman extorting money from husband after khula

Q: My (ex) wife asked for khula to whom I provided for 14 years as per my duties. I have never been abusive to her. I agreed to providing accommodation (3 bedroom house) and maintenance as asked of me under sharia until the youngest kid is 23 years old of my 2 kids.

My ex isn't happy with sharia solutions, avoids going to scholars and taking me to British court for my assets (£550k). She wants a permanent house in her name + extra money and putting me in much financial hardship.

What advice would you give to my wife? Would she be sinful for taking me to court after I have been sharia compliant? Would the money she gets from the court be halal for her?

Her parents are financially helping her with legal fees even though I have been sharia compliant, would they be sinful?
