NIAGARA FALLS, Ont. — Sexyboots, as she prefers to be called, admits she’ll be committing adultery in Niagara Falls this weekend.

But she won’t be cheating. In fact, her husband will likely be in the same room nodding with approval.

This is how they keep their marriage strong, she insists. And their swinger friends, who they know very well, tend to agree.

“Most of our friends have been married between 22 and 12 years, and have been in the lifestyle for at least five,” she said from her home in Toronto.

“People naturally lust after more than their spouse. Some act on it without consent and have affairs, some repress it, some acknowledge but don’t act on it.”

“I’m not advocating this for everyone — you have to be able to trust your spouse implicitly.”

Sexyboots, 37, and her husband will be among the hundreds of couples expected to attend this weekend’s Valentines in Niagara erotic convention and expo.

Organized by the swinger-friendly website OntarioCouples.com, it will be held in an undisclosed hotel to protect privacy and keep undesirables away.

Privacy is key to an event like this because some couples are still experimenting and don’t need the added scrutiny, Sexyboots said.

Others simply don’t know what they’d tell their friends and family if their secret was revealed.

“My family would not be shocked, partially because they know we have a good sex life (and) they are so liberal and open-minded,” she said. “His family would be appalled.”

Several seminars are scheduled for the expo, including pole-dancing classes and a tantric sex workshop. The entire three-day event costs $598 per couple.

While Sexyboots said sex is definitely in the air this weekend, it’s also a chance to do the “regular” couple thing and visit Niagara Falls.

“It’s a mini vacation for many of the couples. No job, kids, parents, in-laws, housework, errands — just you and your honey and whatever you want to do.”

That suits Niagara Falls Tourism just fine.

After an initial chuckle, executive director Anna Pierce pointed out swingers are tourists just like everyone else.

“We definitely welcome all visitors to Niagara Falls, and we’d like to feel that we’re open to any groups wanting to come and enjoy our city,” she said.

“As long as it stays in the comfort of their own suites, we’re fine. It’s a good, strong group of people, and we can definitely use the business.”
