Adjustable head

Sooo, looking to buying an Aneros massager, was wondering if any have a movable/adjustable head?
Turns out I’ve been overshooting the length with my current toy and if I hold it about two or so inches out things feel MUCH better (I had got a hint from this as things always seemed to feel more intense while the toy was slipping out)
For comparison, was dry for 35 minutes but started leaking almost immediately when I changed to this position. So I was wondering if there was a massager that
A. Has in insertable length of 3-4 inches at the head
B. Doesn’t easily slip out even lubed up (vibration optional) hands free
C. Has an adjustable/moving head so it can better hit the correct spot
