XBiz - The Industry Source: "“sex” itself still dominates all individual search words, with more than 300,000 surfers every day over a 60-day period submitting queries that contained “sex.”

“Porn” was the number-two individual word, showing up in around 235,000 queries per day.

Other adult-oriented words in the top 10 include “pussy” at number four with 175,000 daily occurrences and “milf” at number six with around 140,000 searches."

What can I say, sex sells! To bad we can't channel all the energy spent in sexual self satisfaction to some good causes like cures for Cancer or Aids. Of course without self satisfaction we may get more cases of Aids and prostate cancer.
