Rosewind,
As you go through the site, I think you will find that there are many ways that people/furries express themselves. Not all furries even have a fursona (online personality).
Many furries enjoy to roleplay online through MUCKs like FurryMuck, Tapestries and Furcadia. You can either role play as your fursona or develop many different characters to play as. I can be found on Tapestries and Furcadia every once in a while.
Many express their furry side through art like the webcomic you are creating and writing. I draw and write a little myself as well.
In real life you have furry conventions and gatherings for socializing. Some people will wear ears and a tail at times, which is not something that I do. I have some furry art on my computer at work, but that is one of the only visible displays of my furriness that is publicly viewable.
