TORONTO - Mark McIntyre is used to receiving horrified looks when he greets people at the door. But he hopes that'll change soon.

McIntyre has become pretty comfortable engaging with others while almost naked as he enters the final stretch of a 25-day web stunt called "The Guy at Home in His Underwear."

He's not an exhibitionist and doesn't particularly enjoy the sensation of being constantly watched -- while shirtless and pantsless -- but the cancer survivor swallowed his pride for a good cause.

With a sponsorship from the underwear company Stanfield's, McIntyre has raised $50,000 for the Canadian Cancer Society and hopes www.Guyathome.com has spread some awareness about testicular cancer, which he was diagnosed with a few years ago.

Although McIntyre, 41, has a theatre background, he said on Friday morning -- Day 24 of the campaign -- that it wasn't easy putting most of himself out there for all the Internet to see.

"There's nothing that ever prepares you for this," he said during a telephone interview, which like everything else he does, was broadcast live.

"You sort of get used to it a little bit, I guess, but at the same time I think it's really surreal and for the next two weeks I'm probably going to be looking over my shoulder thinking that people are watching me."

Most of the time, McIntyre's sequestered life was mundane, and he spent large chunks of the day sitting at a computer chatting with viewers to pass the time. To spice things up, some activities were scheduled for him, including a psychic reading, a blind date, lessons in yoga, belly dancing, volleyball, playing the didgerydoo, and a birthday party.

To raise extra money he also took part in a few challenges, including frying up bacon, having his chest waxed and getting a tattoo.

He admitted to doing a bit of clock watching over the past few days and was itching to get outside and go for a long, long walk. After putting some pants on, of course.

"I'm a total walker," he said, "I feel like a little bit of a caged animal in here sometimes because I walk everywhere ... and without that it's been really bizarre for me. So yeah, I'll probably go for a nine-hour walk."

The end of McIntyre's time in front of the cameras will come Saturday afternoon sometime around 4 p.m. ET, after accepting the $50,000 cheque and saying his goodbyes. He's glad he had the chance to share the story of his cancer diagnosis with countless people around the world -- no viewership stats were available for the website but his Facebook page had more than 51,000 "Likes" as of Friday afternoon -- and hopes some of his followers are now aware of how testicular cancer strikes young men.

According to the Canadian Cancer Society, about 900 Canadian men are diagnosed with testicular cancer every year. While most are between 15 to 29 when they discover they have the disease, McIntyre, who works at a Toronto comedy club, got the cancer later, at 38.

"No matter what the statistics tell you, you should always be checking," he said.
