Dick appointment?

So I’m thinking about making a dick appointment but the location is sort of a problem ... So my boyfriend lives with his family and his grandmother, his mom and dad are cool with me coming over, staying the night, etc. but the grandma is HOLY and is like HELL NO, can’t even watch tv in his room 😂 and at my house I live with my dad and he’s ok with company but of course not staying the night. Nobody wants to think their little girl is having sex and especially not in his house. So I want to sneak him in. My room is the carport of the house , refurnished and all cute and girly .. but my bed makes too much noise. I have 2 sofas in my room though. I have like a living room area & a bedroom area. I have a lock on my door but I’ve never had a reason to do it, and another problem is that the bathroom is in the dining room with is next to my room but more connected to the house . Lol what should I or how should I do this 😂 we’re both “ grown” just live with our family. We aren’t 16 or anything sneaking to have sex . We use to get hotels but it’s like a waste of money
