'Captain America: The First Avenger' actor Dominic Cooper has revealed that he prefers to film sex scenes "butt naked", rather than wear a "sad nappy". The actor revealed that while filming he has been asked to wear a variety of embarrassing undergarments in order to protect his modesty, but prefers to go 'au naturel' and throw modesty to the wind while filming love scenes.

Cooper answered the question as to what there is to be embarrassed about in a sex scene, by revealing to 'BANG Showbiz' that: "Well normally it's what they try and make you wear, which is anything from some sad nappy, to a towel with elastic bands round it in the shape of a penis - like that in any way is going to make you feel better. Actually, it's better to be butt naked and get on with it.''

'Fleming: The Man Who Would Be Bond' stars Cooper as writer Ian Fleming, in the run-up to the completion of his first James Bond novel. Throughout the television miniseries, Cooper has a series of sexual encounters with 'Sherlock''s Lara Pulver. The 35-year-old actor insists that he was, luckily, never inappropriately aroused by the filming - all thanks to the decidedly unromantic atmosphere on the set.

The upcoming 'Agent Carter' actor explained that: ''I've been quite lucky enough to not have [been aroused]. I think probably when I first had to do it that was a real fear but you learn quite quickly that you are surrounded by hairy blokes with cameras in their hands and microphones, and it's the last place you would get aroused. Plus you're not doing it with someone who you should really get aroused with anyway.''

Cooper's portrayal of the James Bond author can be seen on 10th March, 2014, with the DVD release of 'Fleming: The Man Who Would Be Bond'.
