The Super Head Honcho is pretty intuitive. I'd just suggest not to skimp on the lube -- a little is fine, but a little more feels great. You can either stay inside, or pull it all the way off and on for added stimulation.

It's made of a jelly-feeling TPR and is nicely ribbed inside. It does have a light, sweet smell to it, but that doesn't bother me at all.

The design was perfectly fine, as was the size. I'm an average guy and it worked well for me. I just lube it up and it stretches out perfectly fine and once I'm in, it accommodates me nicely while maintaining a tight, but not too tight, grip.

I actually don't look at the instructions for this kind of thing. (I know, how horrible of me.) But, I just wash it with soap and warm water and it has been just fine.
