warning ⚠️- photo - anal sex aftermath

My husband and I had a one time let's get drunk and have fun event for my birthday. Well things got a little kinky and we ended up having anal sex. We have before but once every 6 months and usually with a lot of lube. THIS time we couldn't find the lube. He used saliva and obviously that wasn't enough. I remember having him stop because it ended up hurting too bad. But three days later and every time I have a bowel movement I see this. It doesn't continue to bleed and goes away after a wipe or two. Can I assume I have a couple small tears or something inside? Should I be extremely concerned? Will it heal on its own?
