It is permissible with certain precautions to speak in print of coitus, but it is not permissible to employ the monosyllabic synonym for this word.

If he holds them because his elders told him they were true when he was young, or if he holds them because if he did not he would be unhappy, his thought is not free; but if he holds them because, after careful thought, he finds a balance in their favor, then his thought is free, however odd his conclusions may seem.
