Best positions for anal🙈

I've had anal a little more than a handful of times & only twice it has felt good. every other times was uncomfortable or painful. Yes we use lots of lube or coconut oil & go slow & he also makes sure my vag gets proper attention too😂 but I'm wondering if there's more comfortable positions? We've done it doggy style, me laying on my tummy, & from the side. Any suggestions ladies?😇
