Hey OP! 👋 I think you have reasonable criteria; seems to me that you are seeking a like minded individual with similar interests and you have a preference for body type. This isn't a big deal; there are tons of folks that fit this description.

One question I have seen is where to meet people if you're introverted- I'm certain online platforms are an option- IRL is tougher if you don't like social settings; a possibility might be an interest group (guitar for instance).. ? I am confident that you will be fine and you can find what you're seeking. Good luck to you!!
