The 34-year-old actress, who has appeared in a number of racy scenes in her films, said she is not usually comfortable baring all, reported Contactmusic.
"It's kind of weird I get so much into the character and so passionate that I forget... If you're talking about a nude scene I get numb in some way, I forget that I'm naked and I do not like being naked," she said.
However, the 'Penny Dreadful' star, who stars in the 2015 iconic Campari calendar, which is titled 'Mythology Mixology', insisted she wouldn't strip if she didn't feel it necessary for the role.
