The woman also with whom man shall lie and have an emission of semen, they shall both bathe themselves in water, and be unclean until the evening.
Read Chapter 15
Clement Of Alexandria
AD 215
In the past, a man coming from marital intercourse was required to wash. It cannot be too strongly said that the providence of God revealed through the Lord no longer makes this demand. The Lord eliminates washing after intercourse as unnecessary since he has cleansed believers by one single baptism for every such encounter, just as he takes in the many washings prescribed by Moses by one single baptism. .
