Selfish? Have I already gotten my reward

So my wife is out today getting a massage and a facial and doing some shopping. While she was gone I scrubbed all the floor and cleaned up house. The while time I was thinking about how I may earn some teasing tonight, but given how my little thing was trying to get hard the whole time....have I already gotten my reward. Probably knowing I will please my wife in one of the only ways I am able is reward enough?
