Is it normal to not want people in your house?
Mostly.Normal for most people
Yes, it’s normal to want your home to stay private and not enjoy having people over. Some people love hosting; others prefer to meet friends somewhere else, and both are fine.
Your home can feel like your one place to fully relax, so having guests may feel disruptive—even when you like the people visiting. Lots of people would rather meet up at a café, go for a walk, or be the guest instead of hosting.
You don’t owe anyone access to your space. A simple “I’m not hosting, but I’d love to meet up elsewhere” is a perfectly good boundary. If avoiding visitors is making you feel lonely or is driven by anxiety that’s hard to manage, it may be worth looking at what’s behind that—but simply preferring your own space is no big deal.
