Sexlexia
A mental disorder where a person sees connotations for sex everywhere, principally within literature. The term can also be applied more generally to encompass all forms of communication and social life. 
The concerned person will be very disagreeable and will, unconsciously, relate everything you say to him, to sex. He will be incapable of any clear thought whatsoever. 
Certain people believe that sexlexia may cause an irreversible modification of the brain, which will block the victim from clear thought for the rest of his life. Specialists disagree over the cause of the illness, but it is most commonly believed that Sexlexia is not only influenced by the social lifestyle of the victim, but also by the size of his penis (very small).
