Sounds like restless legs syndrome to me! Some people think restless legs is a forerunner of neuropathy, but one way or the other, that's what it sounds like. It can be agony, it can be relieved by massage, and when it's gone, well, it's GONE. And if he's being frisky, not just FEELING frisky, why, then the restless legs wouldn't be in a position to be restless at all.
Without being too glib--sounds like you guys have worked it out. You massage his restless legs, and he feels better, and, in addition to better, he feels bonded to you and connected to you, and ready for fun, the ultimate cure!
Enjoy!

PS. I had restless legs when pregnant, and the only thing that helped was my husband rubbing them hard. Don't recall what happened after he did, however....
