Is this wrong?

Dayana

My cousin lives with my dad and uncle and my brother, I come up on weekends but my dad continuously tells my cousin not to have sex when I’m over because of me and my brother, my dad is sleeping at a friends house and him and his girlfriend are having sex and I was trying to play my ps4 on my dads big tv and I heard moaning and I yelled like can you have some respect, and she started moaning louder, now the girl has kids but always comes to our house like it’s a whore house, she’s all nice but doesn’t have the decency I’m 15, I’m sexually active myself my mom knows but I currently wouldn’t like to tell my dad yet, but my brother is 18 but we don’t like hearing that, she always comes late at night

Is it gross and disrespectful?
