When my wife first saw this sleeve, I felt like she had just seen her first giant **** unzipped...that sort of slight shock~definite desire~that's going inside of me? look. At least there was no jealousy, because I would be the provider! We have been enjoying smaller textured sleeves for a while now; this one's a definite girth increaser, with pretty hefty ridges but they are soft enough to work gently enough on her ******. We put the long row of ridges along the top, so that she can ride along it as she cared to in cowgirl, and she gets off very quickly (reversed it once for doggie, and that popped off an ******, too, with just a little more work - but still got to the end zone). Kind of an odd, though not bad, sweet smell to the rubber when new, but with a little use and normal cleaning that faded. Easy enough to put on, I get it all the way to the base of my **** and that leaves a couple+ inches of shaft and head exposed so that I get normal stimulation (actually maybe a bit more, because it does pump up the rigidity and the head a bit). My ******* with it are decent, too, because it's not so tight as to constrict. So is it the greater thickness or the ridges that do it for her?...probably just a combo of both. She is not super small or tight, so with a little lube this eases right in - for smaller ***, probably a little more lube would do fine. Hey, if you weren't born with one as fat as a flashlight, as least you can be that guy when you slip on this sleeve! A fun addition for very little expense.
