Anal tips?

My boyfriend is very into anal and we’ve only done it once. It hurt a lot getting him in.( he’s very blessed on size and girth ) we started with ton of foreplay, butt plugs in different sizes, and lots and lots of lube but when it came to actually us doing it. It hurt super super bad until he finally was fully in. We did go slow easily inching in. But I ended up bleeding for 3 days and wondering what I can do to make it better on my experience with it I’m also terrified of shitting on him 😂(Don’t get me wrong I loved it and finished faster and harder then I ever have lol)

Any tips are appreciated. 🖤
