I bought Doc Johnson "hung" and believe me this thing is huge.
I was so excited to try it , but it is 13 inches long and 9 inches plus in circumference .
It was punishing to insert it , I warmed up on some others first.
Then I got this monster out and never thought it would go, but it is very soft, and once I relaxed ,it finally slid in.
This thing has south volume it is punishing to get used to.
But I keep getting it back out when ever I play.
I must like it?
I love a smooth bottle, there are many different sizes , and they all taper.
Chose wisely and go slow.
The bottle can be turned over once you are sized to it.
Average beer bottle is 9 inches in circumference
