This, whcih I have edited, written by someone at the fore-mentioned asexual site, could have been written by me - it so accurately describes my feelings in the past. It doesn't bother me as much anymore, but at one time, I felt exactly like the author.
"...Not being tied down, I have been able to jump at some opportunities for which my sexual acquaintances envied me. I have been able to change careers and continent of residence on short notice without having to consult anyone. If I get a wild desire to drive a hundred miles in the middle of the night for a sandwich, off I go. Whatever. I enjoy, and have always enjoyed, a lot more freedom and creativity in how I manage my life than any of my sexual acquaintances. Being alone, to me, is a walk in the park.
Being insignificant is another matter altogether. I have not been the most significant person in someone else’s life since I was 17. Various people for various amounts of time and various reasons have been the most significant people in my life, but I have not fulfilled that role for another person for almost 40 years. Yes, there are people who love me, who care what happens to me, on whom I can call in an emergency. But there is no one to whom I matter more than anyone else.
No matter how much I matter, someone else always matters more. No matter how much I mean to someone, someone else means more to them than I do. No matter how significant I am to others, others are more significant than I am. Socially, professionally, personally. I am never first to anyone.
Lonely? I can do lonely standing on my head. Lonely is a Sunday-school picnic. Lonely is a walk in the park. Always being less significant, less important, always mattering less than someone else, in every relationship and circumstance in life? That gets old after a few decades.
this is definitely true.
