Metcalfe -- Sex Scenes With Eva Were 'Hard'

Jesse Metcalfe claims the "Desperate Housewives" sex scenes he did with Eva Longoria definitely raised him to another level ... in his pants.

The actor had no bones about sharing his private moments on Jamie White Mornings on 106.5 Sacramento, where he admitted working with Eva made him "pop a wheelie."

The climax of the story -- Metcalfe admitted Eva turned him on so much, he sometimes couldn't get out of the bed when the scene was done filming ... for fear of excessive exposure.

Guess it wasn't a script in his pocket...
