The former Columbus Crew and Leeds United winger retired from the game in February after publicly announcing he is gay but is now back playing MLS, coming on in the 77th minute of the Galaxy's 4-0 home win over Seattle Sounders.
"Earlier today I was a bit nervous. I don't know why. I just had two like hours before I actually left my apartment and I was like, 'Oh gosh.' But once I got to the stadium it felt totally normal," he said.
"The guys made it really easy, they played so well tonight, first half especially. So it made my experience very enjoyable, no pressure at all coming on obviously and just got to enjoy myself and take it all in."
He added: "It was perfect. It was really perfect. We won, which was the most important. My family was here, my friends, my grandparents who live in Palos Verdes.
"I think the first training session the Galaxy ever had on The Home Depot Center pitch I think I was here training with the Galaxy because Sigi was coach so I've kind of been on this huge journey to figure out my life and now I'm back here, I think, kind of where I'm supposed to be."
