Anal Sex Embarrassment !!!

Hey so this is the 2nd time my Bf and I have tried anal to where I pooped on him !! I'm so embarrassed!!! The first time there was a little diarrhea on his dick .. this time I was constipted and after he pulled out there was like some Plato poo on his dick !!! And omg after he fucked without knowing about the poop since it was dark , he goes to eat me out and he's like wtf !! Turns on the light .. and I had a dingle berry  hanging out if my butt !!! He hurried to turn on the lights .. he was like Man Wtf !! Again !! Ahhhh I'm so embarrassed .. maybe this anal sex isn't my thing !! Anyone have similar experiences??
