Making anal more enjoyable

Me and my boyfriend tried anal for the first time this morning and I’m only 16 and he’s 17, I wasn’t expecting to try it this young but it just kinda happened in the moment. It was painful at first and uncomfortable as fuck but as we got into it, it wasn’t painful but I just don’t know if I liked it I was relaxed and we had plenty of lube but I just didn’t feel any pleasure from it. I want to do it again for him because he loved it but I want to find a way to enjoy it myself otherwise it’s just no fun for me, I know it’s not for everyone but I want to do it for him. Plus afterwards for the entire day everything down there let’s say just felt weird, it was sore a bit but mainly weird I don’t really know how else to describe it but that was not very comfortable either. Can anyone give me any advice with no judgement please
