He is too scared

Jessica
My fiance and i found out we are pregnant last week and we havent been intimate since just before we found out. I asked him if it was because i cried afterwards (which we found out why 😊) he said he was scared because it took us 3 years ttc. My sex drive isnt how it was before i fell pregnant but i still want him like before but he seems really scared to. What should i do? Is there any other men out there thats been through this as well?
