Tom Daley insists he is a "gay man now".
The Olympic diver - who is dating screenwriter Dustin Lance Black - revealed in December that he was bisexual, adding "of course I still fancy girls", but has now said he is no longer sexually attracted to women.
The 19-year-old star also explained why he chose to come out in a video posted on YouTube and admitted he was "terrified" of the reaction.
Speaking on 'Celebrity Juice', he said: "I came out on YouTube as I wanted to say what I wanted to say without anyone twisting it.
"I told my family before I told the world. I was terrified. I did not know what the reaction was going to be.
"I did it on YouTube because people were constantly digging and asking questions."
And Daley - who said his relationship with Dustin is "all good" - also recalled an encounter with a woman who revealed he had given her son the confidence to tell her he is gay.
He said: "Two days later after I posted the video I was on my way to Houston to a training camp and this old lady comes up to me in a wheelchair, and wheels over and says: 'I would like to say thank you. You inspired my son to be able to tell me he was gay.'
"I was like: 'Oh wow' and then she goes: 'But he is married with three kids!'
"I was like,: 'Have a nice flight... '."
