Having sex at his dads house ?

Yay or nay ? I stayed the night at my boyfriends last night. He lives with his dad so I asked him if it was ok for us to have sex. He said he doesn’t think his dad would mind.. but I was kind of iffy. I feel like if he allowed me to Stay the night it’s sort of implied but I didn’t want to disrespect his house... if that makes sense

My boyfriends room is upstairs but his father’s is practically right below us. We ended up having Quiet sex but I think my boyfriend was too loud when cumming lol now I’m afraid to face his dad
