Seth Rollins did gay softcore porn before coming to WWE

Would this make him the first openly gay main eventer in WWE history?

​Well that's quite the headline for a post. Although I will say that:
a)  I didn't see anything in the video that would be explicitly gay or porn.
b)  Seth's personal life is his own business and to date he's never made any statements about his leanings one way or the other.  
But to answer the question, Pat Patterson was openly gay in the 70s and headlined for years.  So no.  ​
