Is it normal to feel disgusted by being close with people?

Feelings of disgust, disdain, discomfort etc towards others, relate to how you were raised. Lacking affectionate, present (emotionally, physically, or both) parents/family members, are the result. If one isn't hugged enough or told I love you enough, if at all, exhibit this type of behavior and feelings towards others. In all cases, it was parents and small immediate families, being affectionate. As well as absent, most cases were one parent being absent; if not in both senses, at least one. When a mother or father figure lacked displaying affection / hugging / saying I love you, the result is extreme discomfort for the adolescent as an adult. If you lack the connection between someone as well as are not shown affection, in your formative years, it turns into feelings of disgust/disdain, because when one doesn't experience this enough, it becomes an uncomfortable feeling to show/feel.
In all cases, it was the same parenting; although raised properly, lacking connection with the family closest to them/vacant parent(s).

As you know it's not entirely a "normal" feeling to have, you just don't know the reason behind it. Even asking shows the same interest people I've talked to had/desire to better understand themselves. Most cases, the people who exhibit this behavior, also have great deals of pride, making honest answers hard to attain, and talking about situations from their childhood difficult. There is always a reason behind people who feel like this. But most try to avoid the answers/reasoning behind it. But asking shows the same desire/acknowledgement as people I've spoken with, meaning there is desire to be close, even if you don't subconsciously realize it. You just do not understand discomfort, or why it's experienced.
Most people change their outlook after they mature, 30's, and have family of their own. But before this change, was living detached or refraining from becoming close/making connections, until a breakthrough.
