there is a doctors conference at the local hospital and many are invited. During the conference a man spots a super sexy and fit female sitting with the rest of the people at the conference. After the conference he goes up to her and asks do you want to go out for a drink. "Yes please" she said. Before they settle down for the drink the woman says "I must wash my Hands". So she goes and washes her hands and she comes back and they drink their drink. Next they go for a meal. Before they eat the woman says "I must go and wash my hands". So she washes her hands and she comes back and they have their meal. When they return home they realise they are really turned on by each other and they give in to their throbbing urges and decide to have sex. But before they have sex the women says again "I must go and wash my hands". So she goes and washes her hands and she comes back and they have sex. After they have had sex the man says to the woman "You are a surgeon, aren't you". "Yes" she replies "how do you know that". "well" he says "you are always going and washing your hands". Then the women says to the man "you are an anaesthetist aren't you". "Yes" he says "how do you know that. "Well" she says "because I did not feel a prick"
