How comfortable do you feel "getting amorous" when someone is in another room (of the same house)

My girlfriend and I don’t have a problem knocking boots loudly, even though my neighbor’s bedroom is right next to mine (we share a large 150 year old home with 4 separate apartments). When I was up at my g/f’s family cabin, which is also large, I had a problem with it. Try to be quiet? Not easy. I felt as though I couldn’t relax. Chubby lost.

Do you have a problem getting the job done with your partner, when you’re in a house with someone else?
