I want an actual character. Personality, goals, desires, fears, hopes, insecurities. If you design a 'character' to be just a series of attributes, fetishes, or kinks first and foremost; then that 'character' is going to almost certainly be boring at best, and actively awful at worst. There is no shortage of real pornography or fantastic eroge art out there if all you want is some zero context T&A to fap with.
Also, anyone floating the idea of being a creator with the lead of 'polling the audience' is already off on the wrong foot. Either you care enough to do the shit that you are interested in come hell or high water, or you're just a listless pandering poser. The audience can tell when someone is being inauthentic. Trying to fake a kink is some of the worst kind of cringe. Not just that, but being a slave to popularity pole has to be the most cucked existence for any content creator.
