I disagree with dminer84. I know there are others here that have implants, but they have not followed up with reports of their progress, so no conclusion. But I don't see any reason to think that an implant could burst because of noogling. The only way that could happen is if the implant was filled with air instead of a liquid, or the liquid would vaporise. Not going to happen. I would think that noogling would be a good thing, as some implants leave telltale edge marks that if filled in with breast growth would give a smoother look.
I do think you would want to use a cup that is wider than the implant, at least a little so there is good blood circulation past the implant.
