Olympic diver Tom Daley said it was "love at first sight" when he met his now-partner.
The 19-year-old, who revealed he was in a relationship with a man for the first time this week, also explained that keeping his sexuality under wraps had felt like "a dirty little secret".
Daley told ITV's Jonathan Ross Show, which will be televised on Saturday, that he had made the first move and was not sure if his now-partner was even gay.
Speaking for the first time since he released a video on Monday where he announced that he was in a relationship with "a guy", Daley said:
It really was love at first sight, I'd never felt like anything like it before. We were at a party and I hadn't even spoken to him all night. I didn't know what to do or if he was gay at first. I made the first move, I typed 'call me' in his notes with a smiley face on this phone and the next day he texted. He makes me feel safe and happy, right now I couldn't be happier. I'd never felt the feeling of love, it happened so quickly, I was completely overwhelmed by it to the point I can't get him out of my head all the time. I've never had it before where I love someone and they love me just as much.
He saved me from not wanting to dive any more. After the Olympics I was down in the dumps, as it's such a hard way to get back into everything, but he gave me the extra motivation and made me work harder and that is exactly what I need.
Daley said it was a tough decision to speak out about his private life, but he feels liberated by doing so and has been encouraged by the support he has received.
It was a terrifying decision to make, I didn't know what the reaction was going to be like, I didn't know how it was going to go but I felt I needed to say something. I wanted to say something in my own words and from the heart, I didn't know what else to do. Right now I couldn't be happier, the support and reaction has been amazing, everyone has been so supportive and I just have to thank them. People ask why I had a girlfriend last year, well, it's because I had a girlfriend last year. It wasn't until spring this year that it came upon me, I didn't expect this, it happened and everything clicked and felt right.
He also told the Jonathan Ross Show, which will be screen at 10.45pm on Saturday, that other people in a similar situation should confide in someone.
I felt like there was something wrong with me, I didn't know other people out there felt that way, I felt so alone, so locked away and couldn't say anything. Tell one person. Tell your story, how you feel. I've had people send some lovely Twitter messages with people telling me they've since come out to their parents, that they've had some hope, it shouldn't matter who I'm dating in this day and age. Be who you want to be.
Daley also told Ross he did not want to put a label on his sexuality.
Everything is all pretty new so I don't see any point in putting a label on it - gay, bi, straight, any of those kind of labels. All that I feel happy about at the moment is that I'm dating a guy and couldn't be happier, it shouldn't matter who I'm dating and I hope people can be happy for me.
