I think it would be ok now that we are married, but the last time I was visiting my mom's with my boyfriend (now husband) was in July 1998. And we were in separate rooms (of course this did NOT stop us from getting our groove on! We just had to be on the DL)
Yes, I was 31, but Moms was NOT having the sharing a bedroom thang (even though she HAD to know that we had been sleeping together from the get-go!)
