read, read, read and read some more (then look at pics and vids hoho)
If you are into the idea, i`m sure you read quite a bit all ready and yets face the internet is basically porn so lots of sites you can read up about. My suggestion is find out about yourself first, find the things that turn you on, what fetish's you like etc..
Find out what you want from ya master, do you want to daily tasks, orgasm control via webcam, dominated over email, chat domination etc.. The list is endless and you will find something u think "man thats hot", from there look on sites which specalise in that fetish and look around see the pics/vids etc..
Once you are sorted and what you want and know want you want from master time to start hunting. The getdare.com has list of master/mistress (i see u are bi), post a reply to the ones that interest you and get chatting. Yes online deception is out there and u have to be careful get a good feel on who the person is on the end of the chat.
ANother idea is contact some of the slaves on getdare and ask them to recommand someone to you, this would cut down on online decption. The good news is your a girl, which basically means you will get tons of mail if you post on a forum and you can pick a mistress/master at your own pace.
Take ya time and pick the right one for you and then a whole new world will open up and u will find out more about yourself.
Send me a post if u have any questions and i`ll get back to you, if not GL beepbeep hope u enjoy yourself
