So I've owned nearly every Fleshlight sleeve outside of a number of the newer Fleshlight girls sleeves. For my more detailed discussion of the toy's materials, etc please refer to the Jenna Haze Forbidden review that I wrote. The STU lady is one of favorite sleeves/textures I've gotten from Fleshlight. Some of the textures are overly intense/complicated and this leads to a need for more regular lube application for the toy to be enjoyable.

The STU lady sleeve has a texture that is very intense as it has basically tiny bumps internally that are very close together, this leads a very pleasurable experience during use. Also the way the bumps are laid out/made for this toy allows lube to stay on the parts of the toy where they are needed vs some of the textures they have where the lube can go away from the part of the toy that interacts with the user. This is why I like this toy as it is both an intense texture from Fleshlight, but also pleasant for longer usage.

The classic lady opening is pleasant; however, like many of the vaginal openings for Fleshlight toys it tends to leak lube. This can lead to a lot of lube being wasted.

This toy claims it was "specifically designed to replicate the intense sensations of intercourse, which can help users increase sexual stamina, improve performance and techniques, and heighten and intensify orgasms." I think it doesn't do as good of a job replicating the feeling of intercourse compared to say the lotus textures from Fleshlight. The texture is very intense compared to some of the more basic Fleshlight textures so definitely can help build stamina through desensitization, which if that's a problem for you might be a great choice. I'm not really in need of more stamina; however, I really enjoyed this toy for both it's enjoyable texture and the fact that with such an intense texture it didn't need as much lube as other such intense textures from Fleshlight.
