Ah, sadly I won’t attend Bronycon. But I heard there’s going to be a party floor this year, I think they’ll announce it officially soon! They might have room parties and 18+ panels there. As for actual NSFW art, maybe you can ask other NSFW artists that are going to attend? Maybe they’ll organize something unofficial! That’s usually how it goes at cons. It’s almost never something official or sanctioned. Mostly it’s just a bunch of clop lovers and artists gathering at a hotel room and selling and exchanging stuff!
