How to deal with grieving differently?

I'm quite upset as I'm writing this and I want to know if I'm blinded by my own grief or if my husband is actually acting very inconsiderate. I gave birth to a stillborn 20 weeks old baby three days ago and now my husband is throwing fits because I don't want to do anything sexual with him. I have snapped at him, telling him it's only been three days and that his demands for sexual "favours" are out of line. He says blowjobs or whatever is the only thing that helps him overcome his grief and that I'm not being supportive. He has even threathened with divorce if I don't do it. It infuriates me so much and I start to really resent him for his behaviour. I understand we are both grieving and it's hard for both of us, but I think this is going to break us apart. He refuses any kind of counseling, saying he only needs sexual stuff and I'm creating all the problems by not complying. I don't know what to do.
