A man goes to the doctor and complains that his wife lose interest in having...

Sex. The doctor gives him a flask and warned: "Put only 5 drops in her drink, but no more than 5 understand? Its very strong". In the night, before the wife come home from work, the man make dinner and a couple drinks. He put the 5 drops on her glass but then he thinks: "Was too long since the last time I have sex with her... I will put another 5"... "maybe this doesnt work... 5 more just in case"... "Fuck it, I will not spend another night jerking... 5 more!".... "ups, I already put 20 drops... the doctor said just 5... maybe I will not be able to keep up with her... I will put 10 on mine too". Wife arrives, they take dinner and drink. After 30 minutes the wife rns out of the room tearing her clothes in desperation and screaming:" I want a Man... I want A MAAAN". Right behind her came the husband: "SO DO I".
