Jonathan Bailey finds it hard "not to laugh" while shooting sex scenes.
The 37-year-old actor - who reprises his role as Anthony Bridgerton in the upcoming fourth season of the period drama - insisted intimate moments in the drama are not as "glamorous" as they may seem, and he and his castmates find it much more fulfilling when they are involved in emotional scenes.
He told the new issue of Britain's OK! magazine: "I know the sex scenes have been a hot topic, but as a cast we get more excited by other scenes which require in-depth emotions.
"I know the sex scenes look glamorous, but on set with cameras, tens of people, intimacy coordinators and everything else - it actually feels a bit silly and it's incredibly hard not to laugh."
While Jonathan had his first raunchy scene just three minutes into the first ever episode of Bridgerton and has appeared in a number since, he will only agree to filming them if they are not gratuitous.
He said: "I'm not a fan of, 'Lets get our kit off because we have a scene to film.' It's got to mean something."
Last year, the Wicked: For Good star was awarded the coveted Sexiest Man Alive title by People magazine and he thinks the accolade is "hilarious".
He added: "But at the same time very flattering. I mean who wouldn't be flattered?"
Jonathan credited his six nieces and nephews for helping him stay "grounded".
He said: "When I get to do what the world views as 'normal things' like read them a story or build Lego with them - I don't think they have any idea how happy they make me."
The Fellow Travelers star recently insisted he isn't looking to have children just yet because, as a gay man, he has the "absolute privilege" of not having to worry about his "biological clock" making him feel too old to start a family.
Asked if he wants to have children, he told Britain's Esquire magazine: “There’s obviously loads of kids that could really benefit from love and support.
“I have the absolute privilege of being a gay man — there’s no biological clock. It’s such a privilege, isn’t it, to even be able to have a kid? So, I’m aware of it as an idea, as a concept, but it doesn’t feel very loud in my head at the moment.”
