It is practically impossible to get stuck. With extreme dimensions, however, getting in should be a problem even before getting stuck (so everything is easy and safe). And without lubricant, it is almost impossible to get in even with normal dimensions. At least without it hurting... ;-)

Of course, it's a good thing that none of the Fleshlights have barbs. If it were otherwise, the manufacturer would not have been selling Fleshlights worldwide for over 25 years.

Such an incident has not yet been reported to us and should actually be impossible, otherwise we recommend using lubricant.
