Thinking about trying anal for the first time.. needing some advice!

So my husband and I have been opening up to each other sexually and our life in the bedroom has went through the roof. We have always had a great sex life but now it's all I can think about.

One thing that he has mentioned to me quite a few times over the years is he would like to try anal. I am terrified of the possible pain and if anything will get on him.

Does anyone have any advice for me on how to ease into this or any tips that could make this more mind easing for me? I really want to try it but my nerves get the best of me.

Thanks so much!
