Are there others who genuinely prefer being single, childfree, and independent?

I have a genuine question because I don't know what to do with myself. So, I am 24 years old, and I never wanted children. In fact, I knew when I was 16 that I wanted a sterilization; now, a couple of years later, that urge has grown so much. I once mentioned it to my mom because we are close, and I trusted her, but it turned out to be a disaster. She freaked out about it, and she got so angry that I stopped talking about relationships, about boyfriend stuff, like that, and now I keep having the urge to defend myself whenever the topic comes up.

I feel so crappy whenever that happens. Most of all hurt, I guess. Sure, they don't need to have the same vision, I get that, don't expect that, either, but like, isn't it fair to hope they will accept my choices and what I do with my body? Just like I support my brothers if they want children?

That being said, I am also not very interested in a boyfriend. I have dated a few guys, nothing serious, a few drinks, but I lost interest pretty quickly, and not just with that. Sex is also something that I have no interest in exploring. And I am not a prude. I was kissed once after a date and didn't feel like I wanted it again or was very excited about it. My mom insists it's not healthy, that I am young and need to get out there, find a partner, explore, etc. But I don't want to, I have no interest in it.

Now I am prioritizing what I want in life. My career and I love the prospect of having an apartment all to myself, maybe with a few cats, and when I come home, there's literally no one there. Not saying I never want it, but I want my freedom and not to be tied to anybody or anything.

I guess it has something to do with unresolved issues from my past, in which I had no control over certain situations, and I just love solitude. Even with friends, I like small groups of one or two people, and I don't like going out. Even generally, I prefer to stay at home, read a book, and work with animals, because I love interacting with animals more than with humans (which only adds to the feeling that something is wrong with me).

Are there more people like me who are willing to share their story? Because I need friends or people who understand this. I sometimes feel like there's something wrong with me. Maybe there are also guys who feel pressure of finding a wife and don't want to, idk.
