Please tell me where to post this

I'm new to Reddit. I'm a gay man (A Kinsey 6 and damn proud of it). I'm really struggling to understand a particular straight relationship that a close friend has and I feel lost because I have no personal experience with straight relationships, and have no desire to have one. I really don't feel that it's appropriate to discuss straight stuff here so please point me to the appropriate forum. I have a long standing belief in sacred gay spaces, especially since so many gay spaces have been co-opted in recent years.Where should it be posted?
