Other thoughts... as an introvert, I find it more pleasant when "social" engagements aren't just "let's sit around and talk." For example, I really like board games and cards. You inevitably end up talking about random stuff anyway, but having a focus takes the pressure off. No awkward silences. If you're not into board games, there are a million alternatives... bowling, pool, shuffleboard...
I don't need labels to define me. They're sticky and I hate the glue they leave behind.
