Tom Holland‘s spidey sense wasn’t the only thing tingling on the set of “Spider-Man: Homecoming.”

The actor got extremely candid about the discomfort that came with having to wear a thong underneath his spandex suit in the new issue of ShortList.

“The first thing you need to know, all I have on under that costume is a thong. They brought them in on my first day, like, ‘Here are your thongs,'” he said. “I had serious misgivings – would my arsehole ever be the same again? But I had to get used to it. Even though I was thinking no way, no way!”

And, hearing him tell it, maneuvering the set in his g-string was a daunting task.

“You have to completely disrobe and then put a dressing gown on, but they’re very comfy ones, you can’t walk around in just a thong, can you imagine?” he continued. “And then you race across the lot to the toilet, then come back, get back into it – it’s such a mission.”

Sporting some revealing undergarments wasn’t the only perk that came with the job of superhero though.

“I sign off on lunch boxes, action figures… it’s so weird,” he said. In fact, he event sent one action figure back because it didn’t look like him at all.

“Not even vaguely,” the actor explained. “‘Guys I can’t approve it. Are you sure it’s based on my face?’ I saw Chris Hemsworth’s one, and it looked so good, it looked more handsome than he does, it really was remarkable.”
