Role Reverse

So serious topic and I don’t know what to do!!?!???!!! So my husband and I were trying new things like role reversal. We tried pegging and he sucked my “dick” and we enjoyed it. So he asked if I would eat his ass..... well it was fun and we enjoyed it but as he climaxed he....poo’d in my mouth a little and I really don’t know what to do... do we avoid the convo, do I divorce him? Do I cheat on him? What do i do????
