Adult film star Seth Peterson died suddenly at age 28 at his home in Los Angeles, his grieving fiancé has announced.
“It is with a heavy heart that I share the passing of my fiancé and best friend, Seth. I’m truly at a loss for words, and my heart is broken,” Peterson’s boyfriend, Kobe Marsh, wrote in a post on Peterson’s X account Saturday.
Marsh, an OnlyFans star under the name Cyrus Stark, also linked to a GoFundMe page he had created to cover Peterson’s funeral expenses.
As of Tuesday morning, the fundraiser had hit more than 50% of its $9,000 target.
Peterson — real name Adam Aguirre — was reportedly found at his home, but no immediate cause of death was given.
The gay porn actor launched his career in 2020 and quickly rose to prominence, becoming a well-known figure in the industry and earning multiple award nominations, the Pink News reported.
In his last Instagram post on his personal account, shared on Oct. 25, 2025, Peterson shared a sweet series of pictures of himself with Marsh at Burning Man Festival.
“Had the best birthday with you,” Peterson gushed in the caption.
Many fans and fellow performers expressed their shock at the tragic news.
“We didn’t know each other deeply, but we shared a birthday, which we often spent at Burning Man (with the same tattoos to prove it!), and bonded over our shared love of ball pythons,” adult content creator Rocky Heron wrote on his Instagram story.
“Every interaction I had with him was kind and genuine. I always felt a soft spot for him and saw him as a brother spirit walking a similar path,” he added, while hinting at some of Peterson’s alleged struggles.
“I know life wasn’t always easy for him, and because I saw parts of my own journey reflected in his, I always tried to reach out when I saw him struggling. He was someone with a big heart, a lot of passion, and a depth that not everyone understood,” Heron wrote.
Many followers also paid their respects in the comments under the original post.
“I’m so so sorry. Seth was so amazing and smart and just beautiful all around,” one wrote.
“Very sorry for your loss. Sending you love and strength. I adored Seth and he always came across as such a beautiful and caring man. Rest in peace Seth,” added another.
“I adored Seth. From the moment I saw him debut with Helix, I was head over heels for this insanely attractive and sweet man. My deepest condolences to you, Kobe, and to his entire family,” wrote a third.
