Even if you’re just a bit above average in thickness, then typical fleshlights are way too tight. Especially when you’re also a bit above average in length, because then you reach into the thinner end of the “handle”, which typically has those plastic struts for stability on the inside. You also will kinda push the soft part out when penetrating because the casing can’t fit that AND your dick inside, since they’re designed for small to average dicks.
Male toys suck ass in general though, because they wear and tear so quickly while costing way too much, on top of the exorbitant costs of decent lube, because all the water based shit becomes sticky after a minute or so. And don’t get me started on keeping that shit clean either because it’s like those sticky flobber type kids toys that just gathers up all the dust, fibers, hair, etc. I honestly envy women in that regard, because wearing a dildo down would take some serious effort, and they have such a huge variety of toys too. You can also easily rinse them down in a sink too and most women easily lubricate themselves when aroused, while also being more flexible in regards to erogenous zones that actually benefit from stimulation like vibrations (a vibrator on a dick does basically nothing). /rant
