In my experience with a Fleshlight in the shower, it's not that great!
Granted, the Fleshlight with lube, is man's best friend!
However, a Fleshlight in the shower is a losing combination.
To use a Fleshlight, you need to slather your dick with ONLY water-based lube so as not to damage the Fleshlight material and shorten its lifespan.
In a shower, with hot water and mist inevitably getting on said dick and Fleshlight, HOW THE FUCK are you supposed to prevent the water-based lube from quickly being washed off your dick, winding up with the proverbial DRY HOLE FUCK???
I know this as I have actually tried a shower-fuck of my Fleshlights, quickly finding out my dick begins to stick, and NOT slide, into the pleasure hole! This ended every attempt I made at shower action I ever contemplated with my Fleshlights. It seemed like a good idea at the time, thinking it would be a hot steamy cum, followed by an easy clean-up. IT JUST DOESN'T WORK!!! The lube just washes right off!
This, to me, is just a total waste of good lube, and a colossal waste of jerking time!!!
It almost seemed like a great idea from Fleshlight, but I seriously think they EPICALLY FAILED in their R&D on this particular project.
