Dating 3 months

I've been dating this guy. Everytime we have sec it's mainly just oral and hand jobs. I've asked him if he likes anal he said yes just get nervous doing it. Is this normal? I've told him he can top but he said that makes him nervous also. Is it normal to be nervous even after 3 months of dating? Is there a way to ease him on the subject. I know he said he's done it before and liked it
