How do I tell my neighbour I can hear her?

[BoomBoomBoomLemmeHearYouSayWayOh]

We moved in semi-recently and I can hear my neighbour having sex.

First time I thought it was a one off (maybe his birthday, 😂) as I didn't hear anything the first few months.

But now 2 or 3 times a week I can hear her (only her not him) as if she's in my hallway!
It's not a creaky bed or anything that can't be helped, it's loud, dramatic moans and 'yes, yes' type stuff

I have preteen/young teen kids who can clearly hear her too and it's really starting to piss me off when she starts.

DH and I manage to have sex without the whole house knowing. Never mind the neighbours.

I don't know her that well so I don't know whether to

A) bang on the wall (which I did last time but it was only my fist and I don't think she could hear it over her own squeals, so next time I'll use a shoe)

B) Wait till I see her and say something, which I have planned to do but just not seen her and I feel knocking on her door is way too intrusive. And WTF would I say.

C) put a note through the door. But again WTF do I write?

I feel almost rude asking her to keep it down in her own home but it's embarrassing sat in bed reading, listening to her howling.

A few nights ago DS was sat in bed with me and she started and he was so embarrassed.

Well a neighbour bid leave a note for me once, asking if ' night time activities could be toned down 🤭 ' I was both mortified and amused. However once we were aware we put a pillow behind the headboard. But the giggles increased. I would have spoken to her in person but she blanked me in the lobby so didn't really worry after that

I had this problem - not the screams and moans but the neighbours bed banging against the adjoining wall - usually before they went to work, say about 7 or 8am. I simply tapped (not banged) my walking stick against their wall every time in the same rhythm they were performing at (that lets them know I can hear exactly what is going on) and immediately after they started the banging, and it soon quietened down. I couldn't have spoken to them as he was quite a big (prob why the bed banged against the wall), outspoken guy, but using humour (I thought it was funny anyway) worked. If I saw them later, I just smiled knowingly. I do hope some of the suggestions in this thread helped, as I know how irritating (or amusing - try changing your mental approach to what is going on - hard I know but it might help) this sort of thing can be. A previous next door neighbour was very loving towards his partner (and vice versa - so sweet) and our bedrooms were mirror images but I never heard a thing from them, though I heard drawers opening etc. They were, I knew, trying for a child at the time. So, go figure. Some people just make noisier lovers than others (or are exhibitionists trying for a reaction), I suppose. Good luck
