Ooh, let's see...

You are only allowed to cum on days when you have spent at least 3 hours shirtless in your room or elsewhere in the apartment.

Any time you do exercise in your room you must be shirtless and barefoot.

Maybe on days when the temperature is above some threshold, you should be shirtless at all times anywhere in the apartment including the shared areas? (You choose the threshold in advance based on whatever the weather/climate is like where you are, so that there is a slim but non-zero chance that you will be spending some hot summer days shirtless.)

You should make it a goal that by the end of the year you will work towards regularly being around the other people in the common areas while shirtless with indifference.
