As someone who has worked with Blumas in the past, I can tell you that he
was tested for HIV when he was filming Ice Princess and he came up positive.
He went back and was tested again, and came up positive again.

He's been screwing boys since he was 14, and getting screwed too, and
sucking dicks all along, so nobody was surprised, but it made for a lot of
commotion on the set. But that didn't stop Trevor from continuing to screw
guys, and now he's probably infected a whole bunch of people.

Blumas has a lot of secrets he doesn't want anyone to know, and that's is
just one of them. Here are some more:
