Sleepy Lesbians Next Door
I happen to agree with Robert Lopez, Jeff Marx, and Jeff Whitty, creators of the Tony Award-winning musical Avenue Q, on the subject of apartment living, thin walls, and noisy sex: "You can be as loud as the hell you want when you're makin' love." Or, in this instance, your creepy neighbor with the hipster mustache and his girlfriend can be as loud as the hell they want when they're makin' love. But you and your wife-their annoyed neighbors-can be as loud as the hell you want when they're making love. You can pound on the walls, SLND, make your displeasure known, scream and yell, etc.
And even if your neighbors don't take the fucking hint and quiet the fucking the fuck down, SLND, the noise you make may bring their annoyingly loud sex to a quicker end. The females of certain species-including our own-get loud during sex, i.e., scream and yell, because it helps the males of their species climax more quickly. (Female copulatory vocalization: It is a real thing with its very own Wikipedia page. Look it up.) If his girlfriend's vocalizations are turning your inconsiderate mustachioed hipster neighbor on, the screams of his two lesbian neighbors could push him past the point of no return.
Squicked out by the thought of giving your inconsiderate hipster neighbor an aural reach-around? Look at it this way: The quicker he comes, the quicker it's over, and the sooner you can get back to sleep.
I was in a monogamous relationship with a woman for two years. We split up and remained platonic friends. Months later, on a drunken night, we had sex. At that point, neither of us had slept with anyone else. After we had sex that night, the sexual lion was out, and I slept with two others (using protection, of course). Now my ex-girlfriend and I may get back together, and she has asked the question: Have I slept with anyone else? So far, I have managed to avoid answering and, yes, we are currently sleeping together. Do I tell her?
