Even identical genital acts mean different things to different people. Sexuality makes up a large share of the self-perceived identity of some, a small share of others. Some spend a lot of time thinking about sex, others little.
Some people like to have a lot of sex, others little or none.
For some people, their sexuality provides a needed space of heightened discovery and cognitive hyperstimulation. For others, sexuality provides a needed space for routinized habituation and cognitive hiatus. Some people like spontaneous sexual scenes, others like highly scripted ones, others like spontaneous-sounding ones that are nonetheless totally predictable. Some people's sexuality is intensely marked by autoerotic pleasures and histories. For others, this possibility seems secondary or fragile, if it exists at all.
