Please help!!

Ok so I have wanted to spice things up with my husband for a while and I’ve never done anal, and he’d like to try it too, but I’m a little nervous. I’d also like to put a finger in his Butt and try to make him come while I give him head but I literally don’t know where to start 😂 please please give me some tips if you have done something like this too, how did you approach it? and tips for anal for the first time 😭
