Take a cold shower

You rush to the bathroom, strip off your clothes, scramble into the tub and turn on the cold water. Shafts of freezing icicles seem to stab into your flesh and you cry out with shock.

Almost immediately, your erection shrivels and retracts to almost an inch long as it attempts to seek warmth where none can be found.

You turn off the water. Shivering, you climb out of the tub and grab a towel. Vigorously, you buff your torso as you try to warm up your body again.

The bed looks inviting. You hurry across the room, pull down the blankets and sheet, crawl in and snuggle down.

Within minutes, you're asleep, the events of the past half hour soon forgotten.
