Ha. I knew it before I even saw your post.
Jason is in my top 3 favourite characters on the show. He's the farthest thing from a fag, I think.
There's one scene where drinking a vampire's blood makes him temporarily horny for the vampire (that's what the blood does in the story--happens to everybody) but he seems pretty grossed out by the thought. He fucks Floki's favourite redhead shortly thereafter.
Jason gets all the girls. :)
