Democracy, IME*, is a terrible way to get variety in your characters. On the account that most people will vote for all the options they tolerate, every time, which results in a very similar appearance every time. Or if it's one-vote-per, they'll just vote in whatever the biggest fetish in the crowd is every single time. You will appeal to the largest possible denominator, but you frequently find yourself appealing to only that denominator. Some things are better left to fiat.
*Based on quite a long time running quests on the website Fiction.Live, which uses democratic voting for most player decisions. Questmasters who use voting a lot tend towards two very opposed extremes - all lolis, or all beachbody bombshells.
