I'm salty about family visiting and having sex in my house
Have you told them not to?
I have but they do  not listen to me
It is fine to be annoyed at that. If they are staying at your house, they need to abide by your rules.
Well, it's not that simple. It's my family. You don't understand what my family is like.
Do you have to let your family stay at your house? If they won't follow the rules of your home maybe you should just tell them to get a hotel room instead.
