Was Ennis homosexual before meeting Jack?

Rating: Null/10 (22 January 2006)

I watched this film yesterday, as it was only released in the UK last week, and I was affected by it incredibly. People have said they stopped seeing the two characters as "gay cowboys", and started seeing them as two people in love. I agree totally...this film actually changed my perception on same sex relationships. But I couldn't quite understand if Ennis knew he was gay before he had sex with Jack. I honestly couldn't see any attraction, whereas I could tell Jack was gay even before the tent scene. So did Ennis have any underlying homosexual feelings? Or was it just when he was drunk and Jack kissed him that he realised he was gay? I'd be grateful if somebody commented on this, because i'd like to watch the film again in the future and know when feelings arise between the two. XxX
