Looking for advice

Hi, I am a middle aged woman looking for some advice. This isn't meant to read like a personals ad, I am just trying to explain where I'm coming from. I've been married to my husband for 20something years. Throughout our marriage I have also been with women, and I am thinking of seeking again. The thing is I don't know where to look anymore. Apps never go anywhere. My husband and I don't really do any social activities where I would meet someone. I went to one fet munch and ended up getting asked out by a man. There was only one other woman there and she was straight. Fet is just gross to me anyway, full of dick pics and men who message you when you clearly state you are looking for women. We/I might be interested in some of the events like seminars etc. (not sex parties or anything) but not sure where to start.

We are flexible with our situation, my husband can be involved or not. I feel like I'm the only woman in this situation who can't seem to find other women who are maybe married to men, or single, and are looking for a woman to connect with and have some fun with. I'm educated, relatively stable (lol), and I don't just want hookups, I would really like a long term friendship where the sexual attraction would happen naturally. Any thoughts?
