i shit myself cuddling with my boyfriend and didnt even feel it

i am 16F. it happened a few days ago. i shit myself while i was cuddling with my boyfriend and didnt even feel it come out nor in my pants or butthole. i smelt it, but i thought my boyfriend just farted. i took my pants off, and i smelt it even more. even more obvious now. i laid down on the bed and my boyfriend asked if i shit myself. i said no, because i didnt think i did. he said he seen it smeared between my cheeks. i used my middle finger to swipe and check, and i felt the wet poop all over my finger and the smell got more horrendous. i do vape, so im wondering if thats the issue but its never happened before. i am so shocked i didnt feel it come out. it was all over my boyfriend too and rightfully he was freaking out. i am SO embarrassed i havent pooped myself since i was 11.
