ask him to tell his parents that "We are in 2019 btw"

Their house, their rules.

Oh no! His parents want you to respect their home and their rules /values! It's awful when parents don't want their university student kids to risk getting pregnant in their own homes

I mean i feel for you, but this is so common. Not everyone is allowed to fuck in their parents house lol

So hang out somewhere else. They have a right to do this, and if his parents wont change, he cant help it. It's not worth fighting with him over. You are 23, grow up and get over it. When my now husband and I were dating (in our 30's) and I took him to meet my parent's, we weren't allowed to sleep in the same room because we weren't married. Did we throw a fit about it? No. We respected my mother's rule... because we were mature adults. If this is the worst problem in your relationship things are good. Don't blow a good thing over something so petty.

Why are you still in college? Get a job. And your own place to live

What exactly are you fighting about? Since you have no right to demand they change their rules there is nothing to fight about. Suck it up. Don’t be the girlfriend who bitches to him about his parents. Doesn’t make for good long term plans.

It’s still their house if you and your bf don’t like the rules maybe it’s time for him to get his own place.

For all the rent he is paying, he should get privacy. How much is he paying? Oh...

find what type of music they don't like and play (or sing) it constantly while in his room till "they" ask you to close the door
