S/O staying the night

alright ladies, gentleman and my non binary buddies

My girlfriend and I were going to stay the night at a friends but their mom said that my GF could not because of their mom wouldn’t let a boyfriend stay, and the same applies to girlfriends. I am upset and kind of frustrated because I have a feeling my parents would do the same, but they would make her sleep in another room. So heres my question. Do y’all think it’s fine for your S/O to stay the night? And sleep in your bed?

Bonus: Are your parents okay with it? Do they allow you guys sleeping in the same bed?
