Idk about gooning but the only country specific advice I have is if you have the ability to buy physical eromanga and adult comics, fucking do it, because it's incredibly difficult to import. Precedent has been set that nobody will ever go to jail for it, but people have had normal ass bleach volumes confiscated at the border due to laws passed in the Harper years defining basically ALL manga as potentially csam, and it still makes it difficult to import anything to this day. Doesn't happen very often, but I've heard numerous stories of people getting their stuff confiscated at customs. Part of why I so rarely import doujinshi anymore but leap at the chance to buy Fakku english releases and the like when they're sold here.
