Hi, I'd like some advice from some experienced anal-practitioners please.

I really want to master anal, both me and my partner find it a big turn on but it hurts quite a lot. We've been trying for quite a while, but not that many times, maybe 10 times? We certainly use enough lube and we've tried using Ann summers analyse which supposedly has a mild numbing effect, and once we get into it I'm relaxed but it still hurts. And afterwards I'm usually too afraid to poo because it hurts so much. It's not too bad, I'm strong, but obviously I want to get around this. Does anyone have any advice or at least just have had the same experience at first and can reassure me that it just takes time?

Thank you 😊
