She really likes how this toy feels. It's kind of, but firm enough to insert well. Shaft is about 4" ,knot 2" and the part between base is 1". Her tight muscles are first obstacle. Not quite sure yet, why knot is so difficult to get in. When she is using the wand muscles get even more tensed (around 9:50 it kind of shows). Another time I asked her to take the wand away, she relax and the knot went inside for a moment. She said it kind of hurt a bit. Inch more and I think she would close around it. I need to ask how she felt it hurt. So deep or the size of the knot.
