Anal questions

Before I was married every woman I was with I almost always tried to fuck her butt, kind of a sexy .... see if she'll do it thing. Some defantaly would not, some would but kinda obvious they didn't like it, some were good with it.
My wife of 20+ years was not into anal. We tried 4 times ever and it never went well.
We started mfm fun with a guy we know a couple of years ago....It's REALLY opened out thoughts about sexy fun.
He got her to try anal and depending on her mood she's into it sometimes. Seems I wasn't doing it to her liking.
Seems the guy has to start SLOW, slow pumps till she gets used to it, then him or I can pump pretty good.
Question is....Wife always says pullout slow....why?
And even if I've been going at it back there pretty good...pull out slow....go back in slow..
I get the slide in gently but what's with pull out slow ? She says it dosent hurt but don't yank it out.
