Any advice or tips?

I kinda want to try anal but I’m nervous. I know a bit about it but not on the receiving end. I feel like it would be weird to give him tips while it’s happening. And we both have busy schedules and live with our parents so we have maximum 10 minutes alone together a day maybe, except driving. I want to plan beforehand but our schedules are too dependent on other people’s whimsy as is. I don’t know what I should do.
