I actually almost always prefer tripping alone. My first times tripping I was alone too. When I was with someone else, it was only ever one other person I was EXTREMELY comfortable with. But when I'm by myself I can do what I want, when I want, how I want, and that makes me happier, freer, and more likely to have a good trip. And I know in my mind in case it goes bad that it is just a drug and will end. But except for the occasional exception, I usually like tripping alone. Might not be for everyone though.
