The pair explained to Digital Spy that only footage of "full-frontal fanny flaps" and "extra out-of-the-ordinary things" - having sex with a horse, for example - would make them feel uncomfortable.
"There's nothing in ordinary life that I wouldn't want anyone to see, only extra out-of-the-ordinary things, so say if I was having sex with a horse," Crosby said.
"I would be a bit iffy on that being shown, but everything else is fine."
When DS sought clarification that she meant any illegal acts, the 22-year-old asked: "Is that illegal? But I've seen videos."
The duo also had an "extra out-of-the-ordinary" suggestion for their dream celebrity addition to the cast.
"Jesus would be so cool, because he would kind of disagree with everything that we do so there'd be arguments," Hagan explained.
"I'm not keen on [him turning water into] wine though... maybe he could work out how to do cider."
Crosby and Hagan did also speak about the imminent fourth series of Geordie Shore and its new stars, claiming that club promoter Scott Timlin "slotted straight in" with the group and "pulls more" women than legendary show romeo Gaz Beadle.
However, they revealed that 19-year-old newcomer Daniel Thomas-Tuck "didn't have the easiest time at first" as he was always "trying to compete with the boys".
Geordie Shore returns to MTV tomorrow (November 6) at 10pm.
