I'll try to answer this, good distraction, head is spinning today, had a real bad R morning.

as far as rewards, they dont have to be sex, they can be anything, sex is great though. going back to the bathroom analogy, when its done, stand back, lean against your H's chest so he can hug you and admire his work.

compliment his abilities, his craftmanship, his going out of his way for you. recognize he may have had other plans for his day, but gave that time to you.

one or more of these is good, you dont need to do all all the time. depends on the size of the task.

for small things, a sincere thanks and a peck on the cheek is great. a big hug from behind is nice.

during sex, look up and say, "by the way, this little extra is for helping me the other day."

"In a ham and eggs breakfast, the hen is involved, but the pig is committed".
