TMI should I care anal

So the guy I’ve been talking to for a year wanted to do anal, I don’t like it but I let him do whatever he wants when it comes down to sex. So we were doing it and he was going so far in there basically on my back’ the when he came and took it out he had shit on it and when I wiped it was wet diarrhea type only because obviously mixed with his cum he was so grossed out and just went home and was gonna shower “for an hour” and never heard from him till the next day when I said something still was short’ I’m not embarrassed because u know what anal does. Is it my fault idk is it time to stop talking to him?
