It’s not really so much focused on sex and relationships, but an earlier version of the game had the romance triggers set too low, so it got a reputation for everyone in the game being excessively horny, plus the internet is gonna internet.

I personally had fun with the triggers for other characters saying they wanted in your pants being originally set too low, because I was playing a horribly socially awkward ranger who lived in the woods far away from people, and she had no idea what to do with what seemed like everyone and their cousin suddenly hitting on her. Poor thing constantly had a voice in her head screaming, “THIS IS WHY I LIVE IN THE WOODS!”
