Anna Paquin says her husband is completely comfortable watching her sex scenes with Alexander Skarsgard.

The 29-year-old actress, is married to Stephen Moyer - who is her True Blood co-star - and says that the two men are friends which makes it easier.

"We feel completely comfortable together. Everyone is very respectful of each other's boundaries ... They're all very gentlemanly about it," she said.

Anna, who plays Sookie Stackhouse in the show, met Stephen, who plays vampire Bill Compton, on the set of the program. Their characters were also lovers, but later split up on screen.

Anna - who is pregnant with twins - admitted that she has two sides to her personality and although she will be a maternal parent, she may also get urges to run away with her family: "I have a side that's very nesty. And another that thinks, 'Let's lock up the house and go away for five months.'"
