If you are a strict Christian, oral sex is in fact against the religion. It is a form of Sodomy, like the wickedness perpetrated by the people in Sodom and Gomorrah. In many states, Sodomy is against the law. (Of course, that is nearly never enforced ...). Now, for my own personal opinion, I think in the confines of a relationship between two concenting adults, oral sex should be enjoyed along with other kinds of sex, if desired.
