got a "rush" when he had his first full-frontal exposure.
The 'I Love You Phillip Morris' actor - whose manhood has been exposed in several films including 'Trainspotting', 'The Pillow Book' and 'Velvet Goldmine' - says he felt quite powerful when he stripped off for a play in drama school.
He said: "I remember getting a kind of rush out of that first time, a slight feeling of power about it, you know?"
Ewan - who has three daughters with wife Eve Mavraki - also revealed he enjoys "kissing boys" in his movies as he likes to feel challenged as an actor.
Talking about kissing Jonathan Rhys Meyers
in 'Velvet Goldmine', Ewan told Out magazine: "I remember when I kissed Johnny. It was just a rush at the end of the day. It was just an electrical moment, because you look around and some of the British electrician guys - who are all mainly closeted homosexuals, I think - were sitting around going 'F**k, no.' But I like kissing boys on screen. As a straight guy, it's quite an interesting proposition. Anything on a film set that takes you by surprise like that, that gets your blood up, is good.
"I'm always interested in playing different people, in different situations. It doesn't matter to me whether someone is in love with a man or a woman. I find the idea of love and romance interesting. I'm a sucker for it. I like playing someone who's falling in love because I like the sensation of it."
