Hippocrates wrote around 400 years BC: ‘When a woman has intercourse, if she is not going to conceive, then it is her practice to expel the sperm produced by both partners whenever she wishes to do so.’
This set the tone for men’s thoughts on contraception ever since: basically, it’s up to women, using whatever witchy magic they have down there. ‘Oh, and it’s not just our sperm, it’s your sperm too, darlin’, sort it out.’
