If it's allowed they don't make use of it, up here, maybe it's just because it's hard to clarify what is non sexual (it's like how technically prostitution is legal up here but can't be solicited in public, of which your car is considered. So no street walking. Email and phones though are considered private so escort services with a little extra is completely legal.
also brothels are illegal. So it's legal but the restriction make it less lucrative. Sorry to ramble just thought that was the best example of how it may work). Though I have noticed a few prime time shows using fuck recently so maybe the CRTC lazed up recently.
