I want my uncle to get the fuck out of my house
Have you told him you wanted him to leave?
I have. He has been committing incest and it's terrible.
If you no longer want your uncle to stay in your home then you are free to tell him this. If he is the one committing incest in your family then that is an even better reason to want him out. Dont feel bad about voicing and acting on your opinion here.
I hear ya. I just do not want to sleep with him anymore.
I'm sorry this is happening. Your uncle should not overstay his welcome when visiting. The only way he would know you are uncomfortable is for you to tell him so otherwise he will think everything is okay.
