But this doesn't mean that 100% of all people would thank me. The difference is observation bias. The difference is who we talk to and the circumstances that lead up to these discussions. Often the assumptions are never spoken aloud, and so are even easier to overlook.
I see this issue with nipples, which are an erogenous zone for some, but not all, people. A higher percentage of the kink community seems to enjoy playing with others or having their nipples played with. Since we are more likely to discuss sex in general and nipple play in particular with other members of the kink community, it would be easy to overestimate the size of the nipple-positive fraction of the population.
There's something else happening though. Playing with others nipples is likely to elicit either a light negative, neutral, or strongly positive response. People remember weak responses less, so will have heavily skewed memories. So this will further reinforce misconceptions about the population bias of wired nipples.
This is the same problem seen in political discourse at both the liberal and conservative ends of the spectrum. We tend to enjoy interactions with people of similar correlated interests. This is one reason that the kinky folk find the non-sexual conversations so engaging at the straight munch or gay game day.
It's easy to imagine that the rest of the world has the same nipple wiring that we have. (regardless of whether they are sensitive or not). Imagining a world of differing erogenous zones requires a terrific amount of empathy.
It can be terrifying to discover.
