Help I hate anal

Okay here's the deal, I don't like anal, hardly at all. However, my boyfriend really likes it, and I want to keep trying it for him. Do you ladies have any advice for improving it? We don't have a lubrication problem, it doesn't hurt anymore (we've done it semi regularly since this summer, so it's not a new thing) it just feels like a poop is sliding in and out of my butt, a sensation I do not care for. Any advice would be appreciated. Thanks ladies!
