Also, our neighbor/friend makes hilarious noises during coitus. My boyfriend and I got to hear them last night. She's a squeaker.
My second deployment my living arrangements was next to a married couple, and my roommate and I would hear them all the time. Bless them they tried to be quiet but the walls were so paper thin you could hear a moth trying to silently masturbate. We were pretty good friends with them, so we generally stayed quiet about hearing it to keep it from being awkward.
Except at the end. We found out they were being redeployed back to the states, so the last time they had sex we set up lawnchairs outside and waited until they left their room to go eat, while holding two signs over our heads. A "10.0," and a "8.5 (Lost points for that dismount)"
