Get ready to see a lot more of Jerry O'Connell than you're used to.

The actor, who stars in the new CBS sitcom We Are Men, revealed to E! News that he'll be showing a lot more skin than usual on the series since he's constantly stripping down to an itty-bitty speedo on the show.

"A lot of it is done by the poolside because we're here in southern California and I came into work the first day and there was a very small speedo in my dressing room," the star told us. "It wasn't in the script and I said, 'There's a mistake here. Obviously, you have someone who's Brazilian or South American who's going to be on our show."

And quickly, O'Connell began to get his body ready for the scenes. "I was doing more than sit-ups. I was trying to get as much blood flowing into that area possible. I was doing a lot of grappling...No I did not put a sock in there. It was suggested to me by a lot of people to put a sock in there, so I'm going down that avenue."

The star explained that We Are Men is "about four guys who are recently or currently going through a divorce and live in temporary housing," and O'Connell, who plays a gynocologist on the show, reassured fans that he's done plenty of research to prepare for the part.

"You know my wife had twins so I think that's research enough. I was in the room when they were born. I did not look. I was too scared. I don't go with my wife to the lady doctor these days but I think I've done enough research."

We Are Men premieres on CBS on Monday, Sept. 30.

Tune in to E! News weeknights at 7 p.m. & 11:30 p.m.
