"but I've just been conditioned via society to ignore it and you've been conditioning to get down there and start taking care of it"....
So, you are right and he is wrong because according to you society taught you to ignore it. The same society that taught him to get on with it.
Ever consider he wants a little variety so uses his imagination? Perhaps doesn't want sloppy seconds even though its his own seconds. You aren't going to be "The sexiest woman ever" to him or anybody because there is always a feature on somebody else out there that is just better.
If you wake up next to him doing that, just start doing it yourself and get him in the mood for you. A few moans, he'll be right back into you, or just use your tongue, help the guy out.
