(NSFW) Do you "prep" before '"back door intimacy"?

I have been sexually active for quite a while and have had many partners. I am not shy about it by any means.

Having said it, I have only had anal sex a few times, and it was with a girlfriend who introduced me to the idea.

She was very meticulous about it. She gave herself an enema, took a shower, used scents etc etc before we did it. In that regard, she was sort of my mentor.

My current girlfriend comes from a culture that vigorously suppresses female sexuality. But she is curious about things that she has not experienced, and she asked me if I wanted to do it. I told her I did not really care, but if she wanted to do it, she should do those things that I saw my past girlfriend do ( I didn’t talk about the other GF, just described the process).

She said it seemed like a lot of trouble. And that is OK with me. I don’t need ass fucking to make me happy.

But I am a product of my “upbringing”.

Was my previous “mentor” going to a lot of trouble, or was her preperation a reasonable standard?
