I think you should move back into the marital bedroom and man cave IT up a bit! Dark, masculine sheet and comforter combo. Maybe paint the walls. A drum set in the corner where the highboy chest used to be. That sort of thing.
(This works with other areas of the home as well -- turn a formal living room that's never used into a music room or put a pool table in there, complete with a big velvet "dogs playing cards" wall hanging. )
Women on here, including Greek, have reported how unsettling that was, that her husband wasn't just sitting around pining for her.
