Hot flashes
We have all witnessed the hot flashes that come and go. In my wife's case, we're going on well over 15 years of aggressive hot flashes - so we've just kind of accepted that this is what life looks like forever (she's mid-60s now).
One thing I noticed early on though was that even though she has lost most of her sexual feelings, when I massage her back or am generally, physically sweet to her she'll often get a hot flash and start sweating profusely.
I have always seen that as "Hey, there are some hormones, maybe even the potential for sexual desire, yet there!"
Does this idea ring a bell with anybody else here?
