It can go the other way too. Thanks to the march of time and the health issues that go with it the rest of my body has aged much faster than my dick. The following is a near daily occurrence:
My dick: Let's go bother Eric! Is Nelson home from work yet? Is Chris busy? Go boot up Grindr and Scruff. Who's nearby and wants to play?
The rest of my body: Fuck. Off. ...... We're taking a nap... again.
