fleshlight stigma?

It seems to me that there's a certain stigma in mainstream culture regarding the fleshlight that isn't there for female sex toys. whereas vibrators, dildos and rabbits can be mentioned positively in tv shows (HIMYM, Sex and the City) the fleshlight is usually only mentioned as a joke. It might be a slight towards the idea of men using toys and the fleshlight is just the default name for a male masturbation sleeve (like kleenex for tissues, or Jello for gelatin). if that's the case, why? Is it acceptable for a female to use a toy because the expectation is that women aren't aggressively searching for a sexual partner, but men are the aggressors, so it's a failure to use a toy? sort of like the crocs on Pearls before Swine who eat take out because they're too pathetic to catch zebras? Or is it just because most fleshlights appear somewhat realistic and that is considered creepy? or is it something else altogether? I think its a bit of both of these theories, but that's just me. what does everyone else think?
