I'm actually going to push back on you here. Old people being horny is pretty normal. The fact that we have such an anti-death, youth-and-beauty focused culture in the west results in some pretty shitty attitudes toward elders in general, of which the taboo surrounding old people and eroticism is a particularly salient example. It's funny because Nancy Reagan is so closely associated with a conservative, anti-libertine attitude, which would have frowned upon a woman of any age having multiple sexual partners and engaging in sex acts which are publicly held to be unorthodox or sinful by their fulfilling strictly pleasure rather than procreation.

No you. And don't be ageist.
