As soon as you turn oral sex into a mundane routine and with a sense of obligation, even the most skillful techniques lose their effectiveness.
Following a survey conducted on a large group of men in Bilbao, the results showed that the majority would prefer one memorable blow job once in three months, as opposed to something mediocre on a more regular occurance - once a week. If we take a look at the statistics, the average number of blow jobs performed monthly in Bilbao is five, with the average couple having sex about twelve times a month. As it would seem, for most men and women, blow jobs are more about variety and discovering new ways to enjoy sex in Bilbao.
