We have 4 and two litterboxes. No issues with them doing their thing. I have had it recommended we need more litterboxes, but since there are no issues, I don’t really see the point. That being said, we religiously clean those twice a day, so I suppose that helps. And on the point of 4 cats, I agree, it’s a bit much. We had two and then last year we found two kittens on the street (not at the same time), one scroungy as hell and the other one had a gaping wound. We nursed both back to health and then didn’t have the heart to give them away, so yea, that’s how that went.
Jokes aside, it’s all about confidence. If anything, fake it 'till you make it. I was terrible with girls for a long time until I stopped caring and just went for it. Then I was amazed how easy it was.
