Oscar winning actor Jeremy Irons wonders if gay marriage becoming legal would lead to marriages between a father and a son.

Irons insists he doesn’t feel strongly about the issue one way or another but says he does have some concerns.

‘Could a father not marry his son?’ Irons asked during an interview with HuffPost Live.

When host Josh Zepps reminded the actor about incest laws, Irons said that ‘it’s not incest between men’ because ‘incest is there to protect us from inbreeding, but men don’t breed.’

Irons, currently starring in the television drama The Borgias, seems far more comfortable with civil unions.

‘It seems to me that now (marriage equality advocates) are fighting for the name,’ he says. ‘I worry that it means somehow we debase, or we change, what marriage is. I just worry about that.’

Irons, however, wishes ‘everybody who’s living with one other person the best of luck in the world, because it’s fantastic."

‘Living with another animal, whether it be a husband or a dog, is great,’ he added. ‘It’s lovely to have someone to love. I don’t think sex matters at all. What it’s called doesn’t matter at all.’
