It has been hailed by some as a landmark moment in Games history and the footage went viral on social media.
The 26-year-old American finished 12th in the slopestyle on Sunday but still found himself making headlines after kissing his boyfriend at the bottom of the slope while the TV cameras were on him.
Thrust into the global spotlight, Kenworthy tweeted on Monday alongside a still image of the now-famous kiss: “Didn’t realise this moment was being filmed yesterday but I’m so happy that it was.
“My childhood self would never have dreamed of seeing a gay kiss on TV at the Olympics but for the first time ever a kid watching at home CAN!
“Love is love.”
The tweet garnered hundreds of messages of support and Adam Rippon, the gay American figure skater, wrote in reply: “Wow okay I just whimpered to myself ‘so beautiful'”.
Speaking soon after the kiss was captured on camera, the British-born Kenworthy reflected on how times have changed in just a few years.
“The only way to change perceptions, break down barriers, break down homophobia is through representation,” he said.
“And that is definitely not something I had as a kid. I definitely did not see a gay athlete at the Olympics kissing their boyfriend.
“If I had it would have made it a lot easier for me.”
He added: “That was something I wanted at the last Olympics, to share a kiss with my boyfriend at the bottom and it was something I was too scared to do.
“To be able to do that, give him a kiss, have that affection broadcast for the world is incredible.”
Earlier at the Games in South Korea, Canadian figure skater Eric Radford became the first openly gay Winter Olympic gold medallist in winning the team event.
