In Part II of my upcoming column on Carnal Nation (Feb. 3), I'll be revisiting my Semen Taste survey and describing the results for a special group of respondents - those who work as professionals in the realm of human sexual behavior. How do they differ from the general population in terms of using protection during fellatio?

In addition, learn about the availability of recipies that incorporate semen, including a cookbook called Natural Harvest, published by a San Francisco nurse. Is this a safe practice? What do you think? This column is an eye opener, in more ways than one.
