pregnancy equals no sex?!?

Ever since I became pregnant my boyfriend LITERALLY has no interest in having sex. I'm super frustrated because I don't know what to do. My pregnancy hormones are out of control. I'll be 16 weeks pregnant on Thursday, and we haven't had sex since I told him I was pregnant. I tried talking to him about it and he says that he knows it's an issue, but hasn't really done anything to help it. I don't know if I'm looking for advice, or if maybe other people are going thru this so I know I'm not alone. Idk. I just feel like I'm broken or something now that I'm pregnant.
