Among the girls and ladies present here are not a few who have not had sex and orgasms for years, some even write that they have never had an orgasm.
Some statistics to consider-
10-15% of women never orgasm.
In the US, something like 0.3% of middle aged women admit to being virgins, but there may be some cultural factors involved with that. The numbers in Japan are higher.
Around 1% of the population identify as asexual, about one quarter of which are women.
While these percentages are all low, when you consider the 168 million women in America and billions in the world, you are going to have large numbers of women who have never had sex or orgasms, or go many years without them, all without any physical chastity devices in use.
