@Nurse_Phillips Guilty as charged, I'm quite anal oriented.
I'm wondering about your age group analysis. I think there are two counteracting factors on this.
Older people grew up in an age where rectal temperatures were commonplace and, depending on the country, suppositories or enemas… not to mention digital rectal exams to confirm appendicitis. So they were used to getting things up the anus for medical reasons. Clearly this created a fetish for me.
At the same time, at the time, anal sex was taboo, and in fact outlawed in many jurisdictions (including many US states). Anything anal for a male was considered associated with homosexuality when I was a teenager, and homosexuality, though legal, was largely considered by teenagers as some kind of hideous abnormality.
Younger people grew up at an age when these intimate medical procedures have largely been phased out.
At the same time, anal sex, dildos, plugs, "pegging" are now, I would not say mainstream, but at least less taboo.
Combine this with the fact that some Western women, in the past, used anal as a contraception method, whereas today it's more like Muslim girls preserving their hymen.
I thus think that today plugs and anal sex are more mainstream for younger people, and anal medically-oriented activities (digital rectal exam, suppositories, enemas…) are more for older people. What do you think?
