When Jokes and I argue we usually don't touch at all until we talk things out. I was recently hurt by something he did and no matter how sad it made me that I couldn't just hug him or have sex, I needed him to really hear how he made me feel and see that I was really affected by it. If I had sex with him while we were arguing to me it would be like waving that white flag. Some people can keep the two separate, but with me if we are fighting then you are going to know you are in the dog house.
Jokes and I try to have some quiet time when we can just talk about things. Usually this is after sex or in the mornings when he is waking up. (I get up way before he does) The talk time is time to talk and try to listen to each other. Although I try not to come across as judging or talking down to him it is really hard to share my feelings with out attaching them to things of the past. Sometimes we just simmer things down and chalk it up to a tie so that we can move forward with life. This can bite you in the rear if you hold grudges *cough* like I do. Still learning how to just live and let live. So for your answer .. no, we don't have sex while we are arguing.
