Humans are social beings. Doesn't matter which culture or country from my experience. Humans have evolved to collaborate and socialize.
If you do a search on these forums, you'll find a lot of posts on this subject. You are not alone in your preference for solitude.
I prefer solitude. I've always preferred it but in order to "fit in" I've had to adjust myself at a considerable negative impact to my health (due to all the masking and scripting and trying to keep up with the speed of neuro-typical conversations, etc). Now I am very selective about when, how and who I socialize with.
I find many neuro-typical people don't understand there is a difference between solitude and loneliness. Solitude is a choice whereas loneliness is not. Furthermore, I find NT's generally have a "if your not with them then you are against them" mentality. However, it doesn't mesh with me and who I am.
For autistics, solitude is necessary for us to regulate, recharge and let down our masks. I do everything solo and don't intend to change.
Don't let the noise of the NTs distract you. Do what makes you happy. There is no right or wrong way to win at life, only what's right and wrong for you.
