Not. Gay. 
He's the Liberace of the 80's era hair era...There has never in the history of the word been a time when assless chaps was hetero...

A couple of weeks ago I did something I’d never done before: I attended a Van Helen concert. Now, I had a Van Halen phase once upon a time — I was always more of a Sammy Hagar guy than a David Lee Roth kind of guy, mind you — but I’d never attended any of their shows.
Conversely, I’ve seen plenty of Broadway shows in my lifetime and this Van Halen show, specifically David Lee Roth’s campy frontman act, was gayer than just about every Broadway show I’ve ever seen. I mean, this guy makes Lloyd from Entourage look like John Wayne.
What was especially striking to me was that most of the attendees of the show had necks that were bright red — this was in the South, after all — but they all seemed completely oblivious to the strong homosexual undertones emanating from Roth when he’s on stage. Like, I’m pretty sure that if some guy wearing makeup dressed in sequined tights came prancing at them Roth-style on the street they’d probably want to fight him.
But because Roth, pictured above wearing assless chaps, is perceived as some sort of swinging dick groupie slayer — and he did make multiple sad, painful references to banging groupies during the show — they were seemingly clueless as to how overtly gay Roth’s entire act is. It left me seriously wondering: how is David Lee Roth not a gay icon?
