I'm the type of guy that always moves with purpose. When I'm done doing something, I'm quick to leave. Looking back on my life so far, I think this has often been mistaken as antisocial.
Every event involving humans is default social. Leaving quickly precludes much of life's social whimsy.
It's a good energy to bring to work or to a crisis. Everywhere else? Maybe not so much. I appreciate you mentioning it here; it can serve me also, as a reminder to work on that.
*Assuming you possess the necessary social skills.
I've trained BJJ consistently for over 4 years now. I think fondly of all the people there and feel accepted, but we barely talk, and I'm unable to participate in the locker room camaraderie.
This is probably not a problem OP has, I just felt the need to complain.
This can be replicated with similar activities that involve a schedule, like joining classes, volunteering, or whatever else fits that kind of setup.
I would try and get something where you can see the results in front of you. I worked years ago at a soup kitchen for the elderly and felt much better for it, than working in a charity shop on a till and feeling like I was just a worker unpaid.
