As an Aspie myself I never actually experience loneliness. In fact, I rather enjoy being alone. However, occasionally I do desire to have some sort of intimate connection with someone else, but I don't really make an effort towards that. I'd rather stay introverted, presonally. As it might be expected as something an introvert would say, I think making new friends and keeping them would be too much work and not worth the effort ultimately, though I understand there are many advantages to having friends. Perhaps I am not very concerned about it because I have plenty of things to occupy myself with in the meantime, including books and music. But, I don't remember the last time I felt I was lonely.
