Get Out There
I already cohost a trivia night once a week at my local, so something different would be good. But almost anything to do with the written word, whether reading or creating, is going to involve more women than men, so not that either. And what else is there, really?
I discovered that as well living in NYC. I eventually met my SO at a biking event. That definitely attracted more men than women. Anything involving books/culture/volunteering (!), however, always had more female attendees.
You could venture out, go door to door, and request that parents let you into their basement.
This is New York. There’s only washing machines down there. Washing machines will never love you.
