When you want to use the head massager you take the end cap off.
When you are using for nipple massager you leave the end cap on.
The purpose of the Head Massager is to create a squeeze and release action anywhere along the head or shaft.
You leave the head open for a blowjob, or hand play or even to use a vibrator on the tip of the penis.
If you are looking for a tighter sensation at the head of the penis:
Try the “float” , instructions are in the assemble booklet.
It is about a 1″ piece of liner that surrounds the receiver shaft liner and floats along during use allowing the head of the penis to pop in and out of the tighter hole.(Some people order smaller diameter liner just for this purpose.
