Really enjoying the comments
Romance / erotica books do not have to be trash, they can very much be moving works of fiction in their own right. But places like McNally Johnson won't buy this kind of stuff even though it does sell very well online. Platforms like Instagram make it difficult as well - Twitter is really the only remaining mainstream platform that will not censor images for pornographic content. You can't use payment processors like PayPal or Stripe either, at least not if you want to keep your money consistently. You have to play a war of attrition with keywords on your site so you can hit SEO thresholds but not set off any content sniffing that payment processors do.
Meanwhile, sell a book about serial killers and everything's hunky-dory. That book can even include heinous sexual transgressions depicted in gruesome detail but as long as you don't have nipples on the cover or 'erotica' in the copy Stripe will cash you out all day long
Well it turns out there are other dads who have made pornography! Who would've thought?
