Frankly, I think you handled it poorly. You should just have called the front desk. And if they asked what kind of noise, all you had to say was they were having really loud sex. Not sure why that would have made you blush.
Blaring podcasts and
YouTube videos? Really? I guess it never occurred to you that if you blared something, then other guests may have heard it?
I still don't understand why you didn't call the desk, then turn on your white noise app and fan at that point.
