I don't trust my partner to be nice and not hurt my feelings as much when we are in the middle of a fight, so I do not try to have intercourse with her at this time. Apparently the sex can be good during reconciliation though, so based on that my advice would be to try and make up and then have sex with him.

Of course, being a woman you have the added option of seducing him into intercourse which I have not tried because it doesn't work nearly as well for a man. Make him a sexual offer he cannot refuse. I think it would be possible to have sex with him in this way. Whether or not it's a good idea is another thing.
