Charity is another passion of mine and I think it's important to give back. I'm a lucky guy, I've had a great life, I have a great family. I'm very blessed that way, so I believe in giving back a lot.

I have to say my relationship with the horses is the biggest thing, and it grows. I love horses more and more every day, and I'm breeding, so when I'm playing a horse that's the son of a horse, the daughter of a horse I used to play, it's like bonding. So I think that's the most amazing part of it. It's the passion that we polo players have for the horses first, and then the game and the strategy of the game and winning and the team and your teammates, all of those things are a big part of it, but the horses are my favorite part.

I started playing polo when I was nine years old. I'm from Argentina, so in Argentina polo is more of a common thing. We have a lot of horses and a polo tradition and it's something that goes from generation to generation.

I'm a really lucky guy, I have a good wardrobe of suits and things, and I have a wife that gives me a direction if I'm doing something wrong. I live a great life and I do what I love, which is wonderful.

Prince Harry is a great guy, very competitive; he's been playing polo all his life. Riding is in his blood. His grandmother loves horses, his grandfather played polo, his father played polo, his brother plays polo, so it's in his blood. He likes to play hard, we joke about it and it's great.

A friend of mine had this idea a few years ago. We thought it would be a great way to promote the sport and to put polo in front of a lot more people in an unexpected place: the romance novel. There's a lot of people that care about those kinds of stories, especially women, and it would help people to know what the polo life is all about. It's not just what you see in the newspapers or on Pretty Woman. There's a lot more to it: the time spent in the barn, how much we love the horses, the relationship with the horses and with the family, etc.

I'm honored and I think the relationship with Ralph Lauren brand has been so long because it goes beyond the face or the guy. I don't feel that I'm a model at all, because I'm not. I'm a professional polo player that endorses a clothing company.
