Is this abusive? Or some sort of bdsm dom/sub

Shae • I love girl talk!
So apparently I had this new boyfriend now, but I'm only allowed to call him sir, master, or daddy... And when we're in private he wants me dressed a certain way ... Basicly I'm his girlfriend, being his "whore" in private... Is this an abusive relationship or is this some bdsm shit, I'm just not use to...
