I'm not OP but I dated the daughter of very conservative parents for several years before finally marrying her. We each lived at home and in fact she moved into my home after marriage because I have an elderly (I was born late) widow as a parent and leaving them behind to rot from solitude was not an option.

I think I can summarize it as: it's never been ideal, but we always made it work, and I'm the kind of guy who likes to remember there are always much worse problems elsewhere in the world. if the worst problem I had to solve was not enough privacy with my gf/wife, then I was doing pretty good on a global scale.
