>>211598978Conference hookups are a thing for single people, but cheating at conferences is probably no more or less common than cheating on their spouses back home. I wouldn't worry about it unless you think she is already cheating on you.
They are becoming less common too. Industries and job roles are becoming increasingly niche, so reputation is becoming more and more important. The idea that you could fuck somebody and never see them again is increasingly fantastical. Even at huge 100,000+ attendee conferences, you're really only interacting with people with similar job functions and responsibility levels as you. Trying to get laid is more likely to make you seem like an unprofessional dope than a stud, at least in upwardly mobile career-track jobs. Especially with Zoomers being massive prudes.
