<p>My hs boyfriend’s mother was open about sexuality (too open … she would greet us and then basically point us towards his bedroom, where we could go for hours without being interrupted … which wasn’t a good thing; we would have benefitted from the proverbial finished-basement-with-footsteps-overhead). If it snowed out, she would offer to call my parents and ask if I could spend the night, at which I always grabbed the phone and said, “No!! Please don’t ever ask that!”</p>
<p>OTOH, when I was in college, I would stay over my then-boyfriend’s now-husband’s house on the weekends periodically. They, like my parents, were much more of the “here, dear, here’s the guest room, sleep tight” and then consciously be unaware of any night time movements. However, they had to have known what was up. One time, now-MIL (who is a major prankster type, and loves to stir up things) came into H’s room at 11:30 at night or something to “fold the laundry and talk” - of course I dived under the sheets, and she sat down on the bed just inches away from my head “to talk.” I am quite sure she knew that I was suffocating under the sheets, and she went back into her own bedroom and she and FIL-to-be laughed their heads off.</p>
