Where is the WordPress Dashboard

I had trouble installing wordpress, and now I have finally installed it. But now I have run into a couple problems. First, when you go to my site Onlinesex4free.com it show’s ” INDEX/ ” then has a link below titled “WordPress”. If I click the link it brings up my wordpress webpage ” Hello World”. I am getting very frustrated, I have two websites. This one is my affiliate site so I would like to “master” wordpress on this site before I mess up my other site. I would appreciate any help, I know some coding and I use filezilla, Note++, But I know idea how to use wordpress or install properly. Thank you
