As far as I know isn't any mod for your concern, but few things you can do against it.
First: timing out with huge value the bothering scenes when they appear (emergency isn't apply the timeout so you should end the scene in normal way)
Second: manually delete bothering scenes from the Poly mod's dir. (the next update will deploy again these scenes if you didn't selectively refresh folders)
Third: as you wroted before, turn off this mod.
Yeah it isn't that i'm bothered by that scenes, or not know how to prevent them, it's more that i'm curious if there is some mod which overhauls the whole poly relationship and adds more events.
At one point i edited a lot of scenes, that was before version 4 tought, but i don't have the time or patience (if i'm honest) to do that all over again.
I've never had a forced swinging scene with poly on, I don't think forced scenes happen with that mod unless you also enable NTR. There's a handful of swinging scenes that occasionally occur but they're all optional. Most scenes with that mod on are just a poly partner introducing someone they want my MC to date.
Unless you've got NTR on then I've no idea why that's happening, if you do have NTR on then that's what you get for enabling NTR
Yes i usually play with most modules enabled (a few like doggy and tentacle excluded), even with ntr active it's easy enough to avoid these scenes normaly, so it never really botherd me.
No swinging scenes aren't forced, althought i don't get why they are in the ntr module, they are a reason i have the ntr module enabled, just swing with a lesbian couple and all is fine
If you are in a poly relationship and have ntr enabled, many cheating and other ntr scenes which are normaly avoidable, locked behind a SO's high perversion or the PC being a masochist/cuck happens all the time and are unvoidable, thats what happening then.
