Follow the script of American college comedies — come to a noisy party and vent out your desire.
You can find privacy in a free room at the friend’s place or, if you are in a public place, choose a dark corner of a crowded dance floor.
At any moment you can be “caught”, so we advise not to drag it out. If the party is quite lively, you can also make noise. But don’t turn all attention to yourself. And in your throws of passion, try not to break the party host’s favorite vase.
