You shouldn't have sex with someone you barely know.
Dirk goes on vacation to a tropical island, attends a party, and meets up with a beautiful foreign girl who wants to go home with him.
Dirk wants to have a good time.
Dirk refuses but continues to dance and party with the girl at the event.
Dirk brings the girl back to his hotel room and spends the night with her, then parts ways with her.
Dirk goes home, gets some good sleep, and leaves the tropical island without regrets.
The girl gives Dirk an STD, cursing him for life, and the one-night stand was unsatisfying in the end.
