Parent telling me my husband and I can't have (mature question)?

I just turned 21 and just recently got married to my fiance and we wanted to see my mom since i haven't seen her in almost a year b/c we live in Arizona and she lives in Florida. She lives with her boyfriend and when we got there, later that night she said no locking our bedroom door (which indicates no obviously lol) Is it disrespectful for a married couple to have in their parents house even if their room they are staying in is all the way downstairs and they are discreet about it? Just wondering...Any opinions are appreciated.
