Hi there. Well, we are all different. That's true. And if you are content and happy, then this path in life is right for you. Some people need the human connection and I suspect you get it 'somewhere' through a relative, friends, etc. But it is what it is. You don't mind being single and sound to prefer it. I'd rather be that way than the type who is constantly seeking to be 'with' someone and falls in love after 2 seconds. But if you find yourself being lonely when you are so unattached, then I'd see a therapist to discuss it. Otherwise, it doesn't sound like a problem to you so it shouldn't be for anyone else. good luck
You've asked the question "what does all this mean?" and you've also said that you'd like to be a little more passionate and affectionate. I really think it's a good suggestion from SM that you talk to a therapist. You mentioned that you live with your folks, and they're not going to be around forever, so you might want to see if you can find yourself happy making plans to have a special person in your life. As we grow older, it's so nice to have friendship with a partner. I hope you find this as well. While your long term relationship was with an affectionate man,there are many men that are not as affectionate and may feel the same as you do about pet names etc.
One thing though, you said that you enjoyed the pet names, and part of loving someone is to learn to give to them, what you accept from them. So a therapist may be able to help your following through with reciprocation. Even with your folks. It sounds like if they want your hugs and kisses, that you were shown that sort of love as a kid.
Did your folks give you hugs, or say they love you when you were growing up. Did you have anything happen in your life that you think could be a reason as to why you are less than "passionate or affectionate"?
