Naked Attraction Viewers Left Speechless Over Oldest Ever Contestant's Explicit Piercing

Watch the moment here:

Before exposing himself, Ian told presenter Anna Richardson that was was looking for a partner following his wife's passing.

Ian also shared that he was interested in both men and women, having had his first gay experience at 70 years old.

After narrowing down a selection of nude contestants to find a potential date, Ian stripped off to reveal he had a number of rather rude piercings.

Anna - and viewers at home - were left open-mouthed when Ian revealed that he had a Prince Albert piercing, two piercings on each nipple, and even a guiche piercing (a piercing on the skin between the anus and the genitals, if you were curious).

He had explained beforehand: "I had 17 piercings at one time. I have six now."

After getting a good look at Ian's piercings, viewers took to Twitter to discuss.

One shocked Naked Attraction fan posted: "IAN WHAT HAVE YOU DONE TO YOUR WILLY?!?! #nakedattraction".

Another tweeted: "I’m actually crying laughing at this episode of #nakedattraction and 75-year-old Ian and his giant c**k ring."

And a third wrote: "F**king hell Ian that's making me wince #nakedattraction".

Others were eager to commend Ian for so boldly taking part in the naughty Channel 4 series in the first place.

One posted: "70+ Ian on #nakedattraction is a refreshing change, and a bit of a surprise."

A second tweeted: "Honestly can’t get over the #nakedattraction episode with Ian. Wow."

A third Twitter user wrote: "10/10 would die for Ian on Naked Attraction #nakedattraction"

And a fourth raved: "Watching #nakedattraction now, loving Ian who is 75 and exploring his bisexuality. What a legend! You go out there and live mate!"
