A tall, good-looking Navy guy in his early 30s moved into the neighboring townhouse a few years ago....our bedrooms back thru the common party wall to each other......within weeks of his moving in, a steady stream of women were spending the evenings at Navy stud's place......at least a couple times, I was awakened to that familiar steady rhythmic thumping we've probably all heard at some point (our bed headboards were directly behind the other thru the wall)......pervert that I am, I'd put my ear to the wall and start, uhhhh, joining in myself.......the thumping would eventually get a bit quicker and then I'd hear a faint few seconds of moaning and groaning from our studly sailor......it didn't take long for me to, uhh, finish, too.....
other than this, construction of these townhouses is sturdy and, no, it isn't a noisy, cheap place.....I presume his headboard was pushed right against the wall (I leave a couple inches)......
he moved away and now rents the place to some very quiet people......
