For a man, nothing can be worse than not being able to rise to the occasion when it matters most in the bedroom. Surprisingly, erectile dysfunction in men is more common than you might think. Whilst it can be an embarrassing thing to talk about for guys, some are brave enough to share their impotence issues. The famous men have all been open about their struggles to get wood...

The 78-year-old actor is 25 years older than his actress wife Catherine Zeta-Jones, 53. And the 'Basic Instinct' star has praised the lord for modern medicine and Zeta for being into older men. He said: “God bless her that she likes older guys. And some wonderful enhancements have happened in the last few years—Viagra, Cialis—that can make us all feel younger!"

The late Playboy founder - who died aged 91 on 27 September 2017 - would pop Viagra like it was candy to keep going in the bedroom. Hefner was not ashamed of using the sexual enhancement pills as he revealed he would not have been able to have several girlfriends at a time if he did not take them. His former twin lovers Karissa and Kristina Shannon revealed that a side effect of the pills left him deaf in one ear. Speaking to The Sun newspaper, Karissa said: "You have to lean down and talk into his good ear for him to understand you. "We could sit right next to him and he wouldn’t have a clue what we said. "Hef said he would rather have sex than have his hearing."

The ‘Friends’ star was candid about his struggles with alcohol and substance abuse in his memoir ‘Friends, Lovers and the Big Terrible Thing ‘ which left him suffering with impotency. Matthew, who started drinking heavily at the age of 14, was left with a dwindling sex life throughout his teens. He wrote: "Sex sounded awfully fun, but it was not in my arsenal.” It wasn’t until Perry got together with ex-partner Tricia Fisher he realised that the rooster could crow but only for a short amount of time. He said: “Sure enough… sheer glory for two whole minutes.”

The ‘Sex Bomb’ singer admitted he started using Viagra at 80 and has no shame of using the blue pill to assist him in the bedroom. Legendary lothario Tom, 82, spilled: "A little help here and it is alright. There is no shame in that at 80. You gotta do what you gotta do”.

The late Brazilian football icon was the first ever ambassador for erectile dysfunction, despite insisting that he never needed to use Viagra. Pele helped raise awareness about the condition which effects hundreds of men, after he started working for Pfizer Pharmaceuticals in 2002. He said: “I haven’t used it, not yet. "My contract was to tell people to use it with prescription not that I started to use it. "At the beginning I was surprised [to be approached by Pfizer] and in Brazil a lot of friends of mine told me to be careful and to find out what is the real message, what is the real campaign. “But when I was in New York I got all the information on the situation all over the world and I thought that it is good to be part of this."

As the face of Giddy – a “wearable Viagra” - Danny has no shame in admitting that he has suffered from ED, a side-effect of his cancer battle. 'Machete' star Danny, 78, is adamant that almost every guy has had this problem on occasions. He said: “Every man on earth has experienced this, and if you say no, you’re lying and I’m calling you a liar. So there you go Danny Trejo called you a liar and now you don’t have to hide it. “It’s like macho means you can always get it up but I don’t care who you are. You can be 25-years-old and if you’re tired, you’ve been working all night, it’s late - sometimes it’s not going to happen."

Outkast rapper Big Boi was arrested back in 2011 as he was coming off a cruise ship in Miami. After being thoroughly searched, he was discovered to be carrying ecstasy, MDMA and Viagra.

Last year, Johnny sued ex-wife Amber Heard for libel after she published an opinion piece in Washington Post, which inferred he was a woman beater, a court case which he won.

Documents alleged: “Though Mr. Depp would rather not disclose his erectile dysfunction condition, such condition absolutely is relevant to sexual violence, including Mr. Depp’s anger."

Eric - the brother of 'Pretty Woman' star Julia Roberts and father of ‘American Horror Story’ actress Emma Roberts - is adamant that ED is not an issue for him, but he has enjoyed the libido boosting powers of Viagra. He said: “My friend John Hoffman, he’s a business partner of mine, he came to me and told me he had the cure for ED. “I said, ‘I don’t have ED.’ He said it didn’t matter, and told me to try it. I tried it once, and it worked. “I was embarrassed, of course - and so I tried it a lot - and every time I used it, it worked.”

The three-time Super Bowl champion - as player and coach - suffered a heart attack back in 1988 whilst he was in charge of the Chicago Bears. Ditka recalled the first question being asked after his heart attack was whether he suffered from impotency and admitted the Ddctor prescribed him with Viagra. He said: "It works. It has some side effects. Levitra is [GSK's] answer to Viagra, but it's supposed to be better, stronger and no side effects. I don't know, I'm just telling you what I've been told."
