Sex Help!!!

Desiree
So my husband has been getting frusyrated with me because ever since i found out i was pregnant i havent been in the mood for sex. But i told him ive been so sick i cant even think of being sexy. Ive lost 20 lbs just from being so nausues i cant eat and i dont think hes being to sensative about it. He says he is but as soon as i say no to sex or not right now he throws a fit. Idk how to tell him hes not being supportive and understanding. Has anyone else been thru this or going thru it?? Help
