Sex during Pregnancy

So I'm almost 8 weeks pregnant and I've only had sex with my husband once since we found out...I asked him why and he said it's weird cause of the baby, I told him sex is safe but he just thinks it's weird.....help!!!! What do I do!!!!! Oh and he also said I don't do sexy things anymore but that I'm still sexy, which is strange cause I haven't changed my habits or my personality so I'm just really confused!!
