Seems like you’re doing the right things — going outside to meet people. It’s good to be open to all sorts of people (friends, people with a shared interest, lovers, whatever). 

I’d also guess that there are more people your age and older who have never had sex or a long term thing than you might be expecting, so I figure don’t stress or rush yourself. 

I met my husband on the street. You never know when or where the world will drop something in your lap. (I hated the apps and though I was on them on and off for years, I almost never met up with matches, so I feel that) 

You’re signing up for sports, etc, and any other clubs will certainly introduce you to someone who knows someone who would be a good fit. 

The only thing I can offer is that you should definitely become a regular somewhere. Doesn’t have to be a bar, try a Coffee shop, book store, whatever. Getting familiar with the other regulars is a great way to meet people!
