Hey :) Thanks for being my first follower of my naughty account. Going incognito with it means I'm starting right from the start again, rather than recruiting the followers from my other account :(
Regarding your bio, less is more. Just write a little bit and it'll be enough. Some people will, but a lot of people won't bother reading a whole profile if it's long. I usually do either of these formats:
1. Age II Where I live (generally) II something I love
or something to that effect.
or 2. a quote or two (or three). In this account I simply did a quote from a song I like that is appropriate with my account. Quotes are a good idea because they're a quick way to find something in common with other people and they give readers an idea of what you like without you having to stumble over how to say it explicitly in a way that's still interesting :)
