Anal. Help. Poo.

So me and my boyfriend tried anal and it smelled like shit. Honestly. And I wasn't expecting it to smell good then I whipped my ass when we got done. And I realized I have shit on not only myself but there was poo on his Dick and he just laughed and I personally don't know how to feel like I'm kinda embarrassed like does this happen is that normal. I basically pooped on my boyfriend and I don't know if I can handle that.
