Welcome to BN! You've got an entire massive website dedicated to answering the question you are asking. What do you like besides Drakkar and how much do you want to spend? The quick, easy answer is to go to the local department store like Macys and check out the fragrances there until you find something you like. If you like Drakkar, you'll probably like Polo or Aramis. Perhaps you may want something more modern, like Chanel Allure/Allure Homme Sport.
Another quick answer is to go to a website like beautyencounter.com, and under 'fragrance' go to 'samples'... you'll find a huge menu of fragrances available by the sample-size.
Good luck, and if you stick around you'll find out more about fragrances than you ever knew existed.
