Personally, I've yet to experience the
Real Deal
However, I have been doing some Anal Training. And what I've found that bigger is not always better ( IMO )
Size does not matter, but rather speed and angle of 'attack'
that makes a Huge difference
The longest toy I've had up my Ass is my current Fav . . The 8" Bum Blaster
Average Girth size, but has an great Mushroom head, and ribbed the entire shaft.
Stick it up all the way up my ass, and fuck myself good and steady. When wanting to CuM...I insert no more than 3 -4 " to tickle my prostate (aka G spot) , steep and fast blasts
p.s. I have rode a English Cucumber, but found the Bum Blaster blasts my Ass, and makes me Cum deeper, longer, harder.
