Everyone has there own definition of sex. For some, oral sex is like the handshake of sexual relations and doesn't count as real sex. In college I heard prophecy of sorority girls at a nearby Catholic college who didn't count anal sex as sex, because the act did not compromise the physical integrity of their holy virginity. Some women do not count all the unprotected sex they had with their ex toward their cumulative sex score as he turned out to be a jerk, and sex with a jerk does not count.
The definition of sex can become increasingly difficult to nail down in the hands of lawyers and politicians. Just remember how convincing Bill Clinton was when he swore he did not have sexual relations with Monica Lewinsky; for him, using a cigar as a prosthetic penis clearly did not count as sex. In Clinton's case, this argument over the definition of sex nearly led to his impeachment. Now the debate over what constitutes sex may raise serious concerns for the Florida legislature.
