I don’t, no, not really. Make up is heavily advertised, and makeup companies have a vested interest in stoking those insecurities to increase their sales. On the dick-size side of things, you have a few surgeons I guess? Some scammy mobile game ads? But the vast, vast majority of people who aren’t fuck-it rich just live with it, the only viable market for that shit is other capitalists, which makes me inclined to think that dick-size insecurities are much more organic.
Hypothesis: if we abolish capitalism and make the transition to socialism and communism, people will still be self conscious about their dick-size, because this particular self-consciousness probably pre-dates society itself
