By 'touch a tree' - is the wire running directly on a tree or is it on an insulator that is attached to the tree? If it is the former, you are losing charge because it will travel down through that tree and into the ground rather than continuing to travel through the wire beyond that point. The latter is fine.
Keep in mind, as well, that your tolerance and idea of a "good shock" and her's are two different things.
