First time anal

So My boyfriend and I tried anal today, a first for both of us. We used lube, he prepped me with fingers first, and I was laying on my stomach with my butt up (Not quite doggy). He slid in easy, I didn’t feel any pain, just discomfort mostly. Especially when he really started going at it I was pretty uncomfortable but it felt ok. But there was blood on the condom and I was bleeding a bit after I went to the bathroom to clean up, is that normal? After we were done it’s been mild discomfort but hardly there, is it okay to have some blood? Will my next poop hurt?
