You crave closeness. Closeness and physical contact increase endorphin's which gives you a feel good feeling and a sense of calm. IT is not wrong ti want to increase the feeling of connection and closeness by cuddling, or saying, "can we just give our issues a rest and hold each other." That will help confirm your availability and exclusiveness to each other even when you might not get along. If it leads to sex that is ok. Most likely your mate will not object. If you can handle sex with someone you are odds with is the big question. Due to my past issues I cannot have sex with someone I am angry with or at odds with. It is damaging and triggering for me. But that is my issue. If you want to have sex and so does he then go for it. It might bring you closer together in this time of unrest.
