he always might've been that way. Like an extreme (sex) freak.
I remember reading an interview of his a couple of years back on i think maxim where he told the interviewer "Did you know a girl can cum just by sucking on your cock?".
I dunno. It is an undignifying way to die, no one wants to go like that, and although now every time i see a David C. film, the way he died may flash in my mind for a sec. but i don't think it's gonna tarnish his acting works for me, like that.
