Ways to prepare for anal sex to make it more enjoyable?

If anyone here has done anal more than once, what ways can I prepare for it to make it more enjoyable? My bf and I have tried anal in the past but weren’t really fans of it. I could never relax enough to actually enjoy it but we have been talking about wanting to try it again because I feel like it COULD be more enjoyable, I think we just didn’t prepare correctly last time we tried.😅 if anyone has any advice let me know!
