The actor - who plays Charlie Pace on the hit US series - explained that he is happy to describe himself as a "metrosexual" and thinks he "should probably be gay".
"I wear make-up and I paint my nails. I wear high heels. This is all true. I like wearing skirts," Dominic explained. "I should probably be gay but I like women too much.
"I am kind of metrosexual in the sense that, if I do get lost, I do ask for directions. I pull over to gas stations and ask. So I don't know. I guess guys have a lot of pride."
