This is actually an interesting legal problem. How would two * willing * co-workers initiate casual sex on a business trip? Certainly this situation has cropped up before! Neither would want to risk their careers on making an unwanted advance toward the other!

Presenting a coworker with a long legal document giving consent to be propositioned, signed with a notary present of course, wouldn't work. It would be sexual harassment to even present the contract for consideration!

They would have to use something like Tinder where they could be both unaware of the others interest until both parties had signed the legal agreement consenting to be propositioned by the other. They would then be directed to do some sort of custom secret society hand sign in the others presence to verify that they had actually consented. The hand sign would be innocuous when seen by someone who hadn't actually signed the contract via the app and seen the secret hand sign the other would display to acknowledge they had signed the contract.

The next billion dollar startup idea?! A cross between Linkedin, LegalZoom and Tinder. The idea would at least make for a hilarious episode of "The IT Crowd" or "Silicon Valley".

Wow, I'm normally pretty sensitive to "this would look bad if the genders were reversed", but I missed this one even though it is absolutely ridiculous and should be obvious.

"He gave several very obvious hints to the woman he was interested in with no response. He finally had to resort to flashing his muscled chest at the woman to get her to acknowledge and fulfill his desires."

How is that not sexual harassment? (Full stop).

I consider it sexual harassment as it is written. The victim's gender matters in the sense that harassment is more likely against women due to the patriarchal character of our culture, but men can still be victims of sexual harassment. They just very rarely ever are.
