Coitus Interruptus
A letter from Lyon on 11.9.1918 wrote “my family doctor recommends coitus interruptus” to which I replied “do not on any account use coitus interruptus. If you cannot get satisfactory help in using the cap you should try a sponge soaked in oil.
I went on to say “The free clinic in London is happy to give personal instruction to anyone who comes without any charge”.
