Currently, there is one pre-made same-sex couple in The Sims series.
These are the typical otome dating simulation games that started the trend (otome meaning "maiden" or "girl" in Japanese).
A same-sex relationship is a potential form of relationship in The Sims series.
Players have been able to create same-sex relationships since the original game, but the way the game has treated these relationships has changed over time.
Is this Sims do become attracted to the same gender in the game, but this sounds more like a glitch. Are you sure this isn't what happened to your Sim?
Not sure what's causing this to happen, and why there's no "I'm a Male seeking a Female" option when doing his profile. Also, try deleting your dating profile and making a new one. The other 49% is moving threads."I have read this on the official forums, where someone's Sim started getting messages from the same sex after one of the Crumplebottom sisters kissed her female Sim in Moonlight Falls.
