Neil Patrick Harris is the guest on today's "Ellen DeGeneres Show" and tells the out host that he decided to come out of the closet last year because he sensed "this sort of witch-hunt brewing."
"There was a little of media scrutiny heading my way," he tells Ellen. "People were starting to ask for stories of other people that may have fooled around with me, and the last thing you want to do is talk about your private life based on scandal. I'm not a very scandalous person and so I didn't want to have to respond to some story, whether it was lie or truth – so I just made a statement and sort squashed the fires."
Harris, 33, had told PEOPLE exclusively in November: "I am happy to dispel any rumors or misconceptions and am quite proud to say that I am a very content gay man living my life to the fullest."
"My life had been relatively open in my world," he tells DeGeneres. "I've been dating the same guy for three years and our families know. We go out together all the time but I just feel like as an actor part of your occupation is retaining a bit of mystery so you can be believable in many different types of roles, so I never felt it was an obligation for me to hold pinkies down the red carpet or anything."
Harris plays philandering Barney on CBS's "How I Met Your Mother."
"He's a crazy womanizer on the show so I just didn't find [my sexual orientation] important," he tells DeGeneres. "But other people did and I sort sensed this witch-hunt brewing."
But his feelings on outing have not changed: "If someone doesn't want to talk about stuff or if someone has reason that they don't want to, I don't think they need to be criticized and chastised necessarily for that," he says, "unless they're blatantly lying about things. I'm not such a fan of pushing, pushing people to make decisions."
"For me that is the greatest ending to the story so far – that nothing really has changed at all," he says. "I'm doing nothing different and people aren't behaving differently towards me. ... People heard and they're like yeah, and? That attitude, I think, was great."
