Anal sex?

The husband wants to try it, I kinda do to but am terrified. I enjoy him playing down there and inserting 2 fingers and it honestly drives me crazy and make me soo arroused. Hence why I am considering anal sex. 
Anyone any input? Have u tried it and what was it like? Did u enjoy it? Was it worth it? Was it painful? If I enjoy him playing down there, will I enjoy it?
