Your problem contains its own solution...
Maybe PCBMan should do his housework in nothing but an apron. Maybe that would help him out.
One week, get a girl to come in and do it for you in shorts and a tank top. Ask the wife what else should you to get outside help to do.
Failing that, wander over to Roissy's place
One additional thought: if doing X doesn't get you what you want, perhaps its time to stop doing X and see what WOULD get you what you want. If nothing does, then perhaps it's time to move on.
Have you tried some "exotics"? (New restaurant for a date, take initiatiave to book a weekend B&B vaca, buy perfume she likes NOT for bday or anniversary...just "because", give a compliment you've never given before, shoulder rub in the afternoon (not just for arousal) when she looks tired, touch her when passing in the hall.
Main thing....know HER and KNOW her needs.
Not saying this is sure-fire, but for many women an answer is DON'T do formula...do FRESH. LISTEN to her heartbeat....not necessarily literally...emotionally & spiritually. Physical can improve after trust strengthens.
