As ladies we definitely get our fair share of embarrassing moments (unexpected period anyone?) but at least we'll never find ourselves caught out like poor Henry Cavill.

In the new issue of Men's Fitness, the Man Of Steel star dishes out some never-heard-before anecdotes including a very cringeworthy one from a few years back. Henry admitted that he was filming a sex scene for The Tudors when he got a little TOO excited and ended up having to apologise to his co-star for getting an erection.

"It’s only happened to me once, and it was very embarrassing,” the actor tells the magazine. "A girl had to be on top of me, she had spectacular breasts, and I hadn’t rearranged my – stuff into a harmless position. She’s basically rubbing herself all over me and, um, it got a bit hard."

Talk about inappropriate. "I had to apologise profusely afterward," Henry admits. "It's not great when you're in a professional acting environment and somebody gets a boner, is it? No, not acceptable."

Despite that unfortunate incident, the actor says that for the most part he finds sex scenes decidedly un-sexy, and doesn't enjoy them. "You don't think of sex scenes as showing your bum to the nation," he explains.

"It's actually acutely uncomfortable being naked in a roomful of people. The very last thing it is is sexy. The actual physicality is very uncomfortable. All you're doing is smacking your nuts against someone, and nothing is going in."

If you haven't been put off by those charming quotes, you might be pleased to hear that Henry is also on the lookout for a serious lady. "American dating is like carpet bombing," he complains.

"You date 16 women all at once and eventually one of them is supposed to pop out of the crowd? I'm 32 years old. I do want to find a wife and raise a family. I prefer the British way: get talking and see what happens, one at a time."
