Yes, many. I had a relationship with a coworker, but it didn't turn out well bc he was not a match with me.
The others were harmless fun. But it was a big company with a lot of employees. The only time work interfered with fun was with my ex, it was a bit uneasy at times but I managed well because it was only via email contact.
About others having crush on me, yes couple of guys, but I didn't like them back and no it didn't affect anyone anyhow. That company was basically allowing coworker dating as long as you disclose it, but no one ever did and many people.. swapped mates, let's put it that way 😅
Work is still the top 5 place to find mates, not allowing people to date their coworkers is silly imo. We're there already 8+ hours. And with the lack of places to have fun and socialize especially with people that are above 25+, it's normal to find love where it might be available.
