I have a geranium that is quite old. I read about cutting them back, but it sounds like mine is too woody. The trunk or stems are very thick. I take it outside in the warm weather and in the winter I bring it in and put it in my window. I don't have a green thumb. Now it is just getting too tall. What can I do. I'm afraid I might kill it. So I thought I would ask an expert. Any suggestions? Thank you

You can safely cut them back if they become too woody. That will be no problem. If you are still concerned that something might go wrong, you can keep some of those cut off portions to start as new plants to replace your older one.
