Just DO IT.
 DO IT.

In all seriousness though, welcome to the site. If you are new I recommend the 1x1 section. It may take a moment to find a stable RP, but it will give you time to think about what you want to do and allow you to really explore yourself without public eyes making you feel small. If it's not for you, you won't stop or slow down a public RP either. I hope you stay around, as I myself joined this site after a whooooole lot of card-shop table top DMing for Dungeons and Dragons. 

Good luck,
