Sex Tube and Gay Tube do sound pretty common.. I bet if it was attempted to trademark it in this day and age where the words are more common... it wouldn't have happened...
I have no issues with the legalities of this.. that's the breaks...
But you guys sound really big and elite and assholish with how you're defending it
The whole, "We just do what the lawyers say..."
Think back 7 years ago.. and how would you have reacted to hearing AFF or Playboy or someone saying that?
