Jesse Metcalfe got so aroused during sex scenes with Eva Longoria, he was too embarrassed to get out of bed.

The actor got turned on by his 'Desperate Housewives' co-star, when they rehearsed steamy scenes for the show between his gardener character John Rowland and Eva's housewife Gabriella Solis.

Asked how he prevented himself from getting sexually excited and "popping a wheelie" during an interview with US radio station 106.5 Sacramento, he said: "It happens. It doesn't happen that frequently because there are a lot of people on set, and it can be very technical, but it happens from time to time."

The interviewer then responded by asking if he suffered trouser embarrassment with Eva.

Jesse replied: "Yeah! As a matter of fact, in the first scene we ever had, where Gabriella and John first had sex, we were rehearsing and then the director was like, 'OK, get out of bed, we have to reset the set', and I was like, 'I need a minute.' "

Jesse returns to the sixth series of 'Desperate Housewives' for two episodes.
