Where to begin…

Hello... only recently that i found this site. I'm a straight submissive slave or "was" but as my submission mentality grew deeper i got realised I'm not good enough to suck any pussy and only good enough to get used by my superiors irrespective of their gender. So i got interested in Masters along with Mistress.. Can i be called as a faggot and what things do i need to do to improve and what things I should focus on serving a Master.?
