I have LOUD sex (and my neighbor HATES it)
My BF just bought a house last year and I moved in right away (we had been dating for a while). Our neighbor is this stuffy conservative couple and their kid (he's like 18). She complained about everything from our lawn to the paint job on the house from the DAY we moved in and even left a passive aggressive note in our mail about our sex noises.
That's when we started having fun--my bf and I started doing it at all hours, extra loud, even playing porn while we have sex. I stopped holding back when I come and even talking dirty. She's called the cops so much that they don't care and apparantly have told her to cut it out.
The best part? Me and my BF have never been better, and I'm having the best sex of my life.
