Firefighters are begging couples to be cautious with their kinky antics after seeing a soar in penis ring removal callouts since the release of the erotic Fifty Shades of Grey franchise.
The number of saucy Brits getting themselves into a Christian Grey-inspired handcuffed tangle has almost doubled since the release of the books in 2011 - leaving them 50 shades of red.
The London Fire Brigade have been called to liberate 23 men with rings stuck on their private parts, and 102 men and women stuck in handcuffs or chained to the bed over the past five years.
In one incident, hydraulic cutting equipment was used to remove two metal rings that had been stuck fast to a man's genitals for three days.

"If the ring doesn't fit, don't force it," London Fire Brigade Director of Operations Dave Brown warned in a press release.
"As well as being painful, you could end up wasting emergency service time if you have to call us out."
Not only is the "Fifty Shades effect" embarrassing, but it is costing UK taxpayers about $530 a visit, which is a total of $1.3million in the past three years.
Overall, fire crews have had to free 459 people who got themselves trapped in "things" - which were often household items such as a toaster and a vacuum cleaner.
A surge in people stuck in the kinky handcuff bind rose from 15 to 27 from 2015 to 2016 and penis ring malfunctions call outs have doubled over the past year.
Turns out the most provocative of the bunch are from Westminister, Lambeth and Croyden.
Firefighter Dave says: "As the second Fifty Shades of Grey film hits cinemas we are once again warning about people being stuck or trapped in objects as penis ring removals soar."
"If there's a genuine emergency, fire crews will of course attend and will be on the scene to help within minutes."
