My advice to you is just type the way you talk in real life, don't sound all proper if you aren't usually.
Don't use slang or talk more urban if you don't usually.
And if it gets a good amount of traffic, move it to a paysite. It only costs about $2.00 a month for a Website.
It'll be much more secure and you can upload pics and whatever else you'd like.
Also, if you are into exhibitionism, you can tell people to periodically ask you to post pics of your cock locked up with whatever word's they choose on a piece of paper, I've seen that before.
You can take dares from your fans and (if your wife is okay with it) occasionally leave it up to them when you can get unlocked, or how your wife should tease you, ect.
