Durex is a Girl's Best Friend

Melody: 

Diamonds are a girls best friend

Lyrics: 

A poke with a bloke may be quite incidental
Durex is a girl's best friend
You may get the works but you won't be parental
As he slides it in
You trust that good old latex skin
As he lets fly non gets by
'Cos it's all gathered up at the end
This little precaution
Avoids an abortion
Durex is a girls best friend
