@KellyandRoger I don’t know if I measured incorrectly, or if this is by design, but the shaft tube is very tight, and at the end of it there is a small inner bump that goes behind the head of the penis to sort of hold it in place. So you have to, kind of lube up your dick and use your finger or some tool to push it through and get the head out the other end. But once it’s in it feels fine.
