I bought one of these after having read that the model with the forearm was very floppy and hard to use. I'm here to say yes, its HUGE and, even for an advanced ass man like myself, it too lots of lube, patience and several weeks of play before I could finally insert the whole thing. But it was well worth the effort! Since my bones won't allow me to use a round plug or dildo much bigger that 2.5" in width, this marvelous toy finally got me that stretch I was yearning for! The design allows a person with a narrow pelvis to insert it all the way and get properly stuffed without the worry that it'll get stuck inside. I highly recommend this and Sammy's Fist as well (even though its a pretty blunt toy and you really need to be opened up prior to playing with it) for those who are into serious anal play. Just don't forget the lube!
