People always assume that when you are at a certain age, you should look forward to dating/courtship/engagement/marriage/sex/babies/family life. Well, I decide that I will stay single for the rest of my life.
I am convinced that I am an aromantic asexual. I experience no romantic or sexual attraction to anyone. In my entire life, only one guy expressed interest in me and asked me for my phone number, but I didn't reciprocate. At the time, I didn't understand why a random stranger who stalked me wanted my phone number. I asked why. He said I looked attractive. I thought he was being a creepy stalker.
Online, one person reports nudity is enough to trigger sexual arousal in a young male. I don't think I have ever been sexually aroused or "horny", even when I see someone naked. Though, to be honest, I have never seen anyone naked before. Sure, there is online porn, which features a lot of naked people, but I always end up thinking, "So, this is arousing to someone? People have no qualms about STD transmission? Where are the condoms? Is that a real penis? Why do people like to shave their pubic hair? Do people seriously get aroused when they engage in unprotected sex?" So, I'm not aroused by naked people in porn.
Given that sexual arousal is required for coitus, I think there is no point for me to be in a primarily sexual relationship. I may get a pass in a sexless relationship. On the other hand, I'd rather not enter any relationship with a male, because of Number 2 below.
If I were male and happen to be in a relationship with a female partner, then I would welcome the prospect of children. At least I don't have to be the one who carries a child for 9 months. But because I am female, having a male partner means I have to be the one to carry the child for 9 months. Plus, I would have to be extremely careful with what I do with my body, because EVERYTHING I do will eventually affect the health of the baby. If the baby is defected, then the defect is my fault, and I will have to support a baby that will never be able to support itself. After the birth, I will have to take care of the child, which leads to Number 3.
3. More Responsibilities
Having a child is a big responsibility, and there may or may not be any beneficial return. A parent is scrutinized and judged by others for parenting practices. A parent must provide more than just food, water, shelter, and social interaction; the parent must provide education, healthcare, toys, diapers, and et cetera. And all these responsibilities occur at once! I'd rather take care of a pet fish and work my way up to higher-maintenance animals, like turtles and hamsters and rabbits and cats and dogs. Then, if I have some spare time and money, I may adopt a child. I think adopting a healthy child is much more preferable for me than having a baby without knowing the risks.
4. Less Money For Me
The prospect of having a significant other and children means less money for myself. I am too greedy and selfish to share resources with another human being. Keeping a pet is different. The pet is expected to respect you. In contrast, I have spoken with some older people who are currently raising teenagers. They say that children respect parents at a young age, but when they become teenagers, they start to rebel and then as they turn into adults, they start looking up to their parents again. Dogs and cats are bred to have a mild temperament, and they will always love you because you'll the one giving them tasty treats. Also, dogs can't eat chocolate. So, all the chocolate is MINE!
