Gay adult film performer Jasper Robinson has passed away. He was only 21-years-old.

Robinson died on December 13 of as-yet-unidentified causes. Sources have indicated that the young performer suffered from a heart condition which could have led to his untimely demise.

In October, Robinson announced that he was retiring from the gay adult film industry, writing on Twitter, “Lol well I’m officially retired from porn. You may be able to catch me on cam sometimes though.”

The (very work-unfriendly) gay adult film blog Str8upgayporn reports,

Robinson performed in dozens of gay porn scenes for Helix Studios, Boy Crush, NextDoorStudios, and CockyBoys over the past three years. He announced his retirement last October, but was still active on social media up until the day before his death. His final scenes were released last summer.

Robinson was remembered by fellow gay adult film performer Phillip Ashton who posted a tribute to Robinson on Twitter,

“I’m still in shock and can’t believe he’s gone. I’m def going to miss him and all the amazing times we had together. Those that knew Jasper he had touched everyone in one way or another. He was a very outgoing blunt one with nature kinda guy.You will always be with me, and those you’ve touched from Oklahoma, Phx, Washington and SF. I love you Jasper and may you always be at peace. Now give them up above what you gave down here. Fly high my beautiful angel!”

He later added that, “Jasper wouldn’t want everyone to dwell on this news. He appreciated life too much.” He also posted a photo of a poem by Gwen Flowers titled “Grief.”

Robinson is the third young gay male adult film performer to pass away recently. In November, gay adult film actor Zac Stevens passed away at 25, followed shortly by actor Dimitri Kane who was only 20-years-old when he died. Both of those deaths have been classified as suicides by officials.

Robinson had tweeted about Steven’s passing, writing that he was “at a loss for words.”
