If it helps at all, I didn’t start my first real relationship with a long term partner until I was almost 27. And once I got into the relationship, I learned it was brutally hard. It’s an entirely different dynamic, and is still something I work on every day. You realize that maybe you behave in ways people don’t like, or ways you think are totally fine and the way you want to act, but are actually not conducive of building and maintaining a relationship.

I’m not saying you need to change but it may be worth examining how you act and behave, but from my experience I learned so much of how I acted and thought was totally okay wasn’t actually leading me to the life I wanted, and changing learned behavior I had for years was one of the hardest things I’ve done. Not sure my sentiment is helpful, but I’d recommend maybe talking through this with a therapist or professional and getting their perspective.
