Grumpy hubby

Ever since we got pregnant even before the positive test, my husbands seemed a bit grumpy.  Today came out the reason why. It's because sex isn't the same anymore. I feel sick all the time so no oral and my bum hurts as it is sometimes so I stay way from back door play as well.  He's mad it's stoped.  In his department he's stoped touching me the way he used to and I don't feel sexy at all so my want to try those things is a zero. I feel like we are in a grid lock.  I don't feel sexy so he Dosent treat me sexy and it goes on and on....   Any advice?  We're almost 11 weeks along and have a long road ahead :/
