Claire Danes admits she sometimes resents being a mother.
The Homeland actress, who has a 21-month-old son, Cyrus, with husband Hugh Dancy, also says marriage is hard, but insists she is besotted with both of the men in her life.
The 35-year-old star told the October issue of UK edition of Harper's Bazaar magazine: "Being a mum is incredibly challenging, but we still feel a pressure to talk about it in very romantic terms. And it's not just that. We all have that resentment at times and anxiety about being trapped by the role, that responsibility.
"And then chemically it can run riot...And there's no 'off' button. [For me] that was the hardest adjustment. You always feel beholden to somebody...And for so long they're like koala bears, you just feel a physical responsibility to be there for them to cling to. It's pretty primal."
Danes loves watching her son grow up, but said he recently started to have temper tantrums.
She added: "It's scary."
The couple got married in 2009 and she thinks being in a relationship is "more fun" than being single.
She said: "I'm genuinely in love with him. And I like hard things. You know, marriage is hard, but I'm up for it. I don't do anything casually so dating is not for me. I would be marrying everyone I was with.
"When I met Hugh I was single for the first time and really looking forward to it, kind of bragging, 'I'm going to rock this.' Then I met Hugh...But I like getting into [a relationship]. It's more fun [than being single]. There's so much opportunity if you are interested in each other to go further. It's kind of a beautiful exercise."
