By your description, you sound rather introverted. Absolutely nothing wrong with that. It doesn't sound to me as if you dislike people as much as you dislike too much social interaction. For you, too much is much less than for the average person let alone a strong extrovert.
My tolerance and preference for social interaction is somewhat higher than that of the average person in this country. My wife is clearly more introverted than myself. For example, she usually dislikes having guests over very much whereas I don't really mind at all. She is particularly loathe to have guests stay overnight.
I am very introverted, but you might be somewhat right about not actually disliking people, but more so the socialising with them. I don't even like to hang out with the closest people all the time, even though I like them.
There are very few people I let into my apartment, I hate having people over. Sometimes I hold afterparties and then it's somewhat alright to have people over, but I make sure to kick them out before the sunrise. Several people have tried to couch surf on my apartment and when I've said no, they try to plea that they don't have any other place, trying to get sympathy, but they underestimate how strict I am about letting people in. So they sleep outside or find another place, I don't care if it's -15 outside, it ain't my problem.
