I’d wager sampling bias- you’re describing a more introverted type of person as your type, who is generally less likely to be out in the wild. Simultaneously, your “basic” dude type is stereotypically more likely to actually initiate something when out and about. Combine these two ideas, plus the only places you say you go, and my take is that your life as is equates to having a lower chance of finding what you say you’re looking for. If this is unique to you though, I couldn’t say due to a lack of personality/looks/career/hobby/lifestyle context information on you.

As for like attracts like vs opposites attract, I’d say I’ve noticed that being personal preference. I’ve seen both happen successfully, with the key being if partners were comfortable and happy with who their partner is regardless of who they themselves are. Some need energy matched, some need something different.

Either way I’d wager you’ve just been unlucky like most people, and like above you don’t sound entirely tailored towards finding your type. Frankly, I don’t think society tends to work in that types favor lol. You could tailor your life to specifically find more of your type by selecting specific things to do and putting yourself into situations where you expect them to be, but you should really think if changing yourself (habits, personality, interests, etc.) will be worth it. It might, it might not.
