My dorm roommate showed up with one a couple years ago. We enjoyed it..................a lot.
Since it was his and he was good enough to share the fun, and cleaning it does take a bit of time, i just used a condom. It may not have been as intense as what it seemed to him, but is was pretty damn good even with a condom on.
Alas, new to the toy and over eager to use it and not as eager once we were spent to take care of it, we had to toss it after a few months. But, at 50 cents a load even, we got his moneys worth out of it.
It doesn't replace a good vagina, nor a firm grip from your hand when needed, but it is just as good and a nice change of pace.
So, with more research on use and care and going into it with the mindset of getting more than our money worth, and armed with his "no questions asked" credit card his dad supplied him with, he ordered us another one with 2 sleeves. No matter how much vagina that is available, it is still a nice fun option.
Clean up doesn't have to be a pain, lots of warm/hot water after use, wrap loosely in a microfiber towel til next time. Use their cleaner every now and then and their renewing powder.
As far as lube, if you can start with a large amount of spit it wont dry out as fast. I don't use the cap for the other end at all, instead i start easing in and out of it with just the lube of my spit, then put a little lube in the other open end. From trial and error we like the KY liquid.
It does get the job done more quickly than about any other way. I like to work it til i cant' take it anymore and am about to blow, then just stop and lay it down, dick still in it. Whether slow work up or fast i like to jerk it off just before i cum and let my dick pulse til it shoots up like a volcano. Then my goal is to be able to stand the sensitivity to push it back down over my dick in its ultra sensitive state without passing out. LOL. I'm getting pretty good at it.
