Sex in the workplace that other people are aware of is not unlikely to be (or be part of, along with other things in the workplace that would be normal absent the sex happening alongside them) harassment.
Unless the sex is a bona fide part of the core business function, rather than an extra-curricular workplace activity.
There's a whole lot of difference between two colleagues consensually sneaking off to have sex and having a fucking designated sex room in the office for everyone to see.
You clearly never understood the phrase 'hostile work environment'.
Otherwise, leave consenting adults to themselves if they're discrete.
There is NOTHING discreet about what you are suggesting. "Oh, excuse us while we go fuck in the designated fucking place at work while y'all keep working. Be right back for the next meeting in 20 minutes."
That is the exact opposite of discreetness and discretion.

Sorry but what on earth is wrong with you ?
Having sex at the workplace is both an Occupational Health & Safety and a Sexual Harassment issue. It is completely and utterly unacceptable in any normal workplace and in most countries it is illegal. The idea that it is part of a company's culture and therefore something people should just tolerate is downright offensive.
