Sex is the oldest form of political power, and provides the shortest path to irrational reactionary thought available to the modern propagandist or political operative intent on influencing culture over generations. Our current ("Western") ideals for how sexuality is to be portrayed by our social institutions doesn't allow for much escape from the negative effects that this power can have over the individual. Hopefully that will change. One way it can change, positively, is for people to learn abstinence culture and just refrain from the act, entirely.

If you never bother attempting to initiate sexual activity, you're pretty safe from those who would use the sex act to alter your life. And if you eschew participating in collective sex-culture, its pretty easy to keep this under control, at a personal level.
