“Somewhere in [his] limbic system ….”

by An Ordinary Man (the novel)

That was what was so comforting about a long-term relationship – your sexual memory was so strong, she was never older than the first time you did it with her; you were imprinted with her as she was then and while you were of course aware of changes over time, somewhere in your limbic system you were still f*****g her as she was when she caught your attention the very first time. That’s why many men continue to wax rhapsodic about the beauty of women who frankly are not so attractive anymore. When men say their wife is the prettiest one in a room full of women, you can be pretty sure either she is, or she’s been doing him on a regular basis all along, keeping the memory of when she was fresh.

Okay, not every woman is going to look as good as Julianne Moore does at 54, but hubby’s limbic system is NOT going to know that: you are still desirable to him, he still wants you, he still needs you (and he might still replace you if you’re not available).
