Not sure if your idea of workplace is good for a young girl that don't want be harassed every day.
If you abuse, harass, or coerce someone, you should be shown no mercy. Otherwise, leave consenting adults to themselves if they're discrete.
Honestly, it is not that difficult to leave that stuff outside the office.
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.
