Ibn ul-Qayyim رحمه الله تعالى mentioned a statement attributed to the Salaf in origin:
A Shaytan met another Shaytaan and said to him:
“Why am I seeing you so thin & skinny?”
So he replied: “I am with a man who upon eating
always mentions the name of Allah so I am unable to eat with him. When he
drinks he mentions the name of Allah so I am unable to drink with him. When he
enters his home he mentions the name of Allah so I (am unable to enter and
instead I) have to sleep outside the house”.
So the first Shaytaan said: “I am with a man who
upon eating never mentions the name of Allah so I eat with him. When he drinks
he never mentions the name of Allah, so I drink with him. When he enters his
home he never mentions the name of Allah so I enter with him. When he has
intercourse with his wife he never mentions the name of Allah so I have
intercourse with her too alongside him”.
عدة الصابرين ص٤٧
[Never mentions the name of Allah upon intercourse - i.e. does not say the prescribed the du’a mentioned in Saheeh Bukhary & Saheeh Muslim:
In the name of Allah, O’ Allah, keep the devil
away from us and keep the devil away from what you have blessed us with.*

or with tashkeel to help us reach the correct pronounciation inshaa' Allaah
*Bismillāh. Allāhumma jannibnash-Shaytān,Wa jannibish-Shaytāna mā razaqtanā.
In the name of Allah, O’ Allah, keep the devil
away from us and keep the devil away from what you have blessed us with.
