"I was bored when she was walking down the aisle. I kept thinking, 'What the hell am I doing here?' " Trump admitted in Tim O'Brien's "TrumpNation," the New York Post reported Tuesday.
Trump -- whose current wife is pregnant -- also revealed he dreams about sex a lot and does not need Viagra to get the deed done.
"I've always said to friends of mine, 'If you need Viagra, it's very possible you are with the wrong woman,'" he said.
