There is no answer. You need to decide. What I told you is not right or wrong it is how I feel. Do you want to have sex with him and keep the current sitch????
If you don’t then yes you need to tell him No sex until the OW is out.
If you like the current sitch then by all means have sex when ever he wants
Sorry there is no easy answer. My W had the affair. I was almost to the point that I was ready to tell her she could have sex with him as long as we could stay together. That is how desperate I WAS. I did not tell her this but it did cross my mind...

And if I claim to be a wise man, well It surely means that I don't know
