Butt stuff

Liv

Hey yall I'm a 19 year old girl and I just had butt sex for the first time. It was without a condom ( my boyfriend and I are clean, lost our v-card to each other) i know this is TMI, but he came inside of my bum and I think most of it came out when I went to the toilet. Is there a possibility it could get out of my bum to the inside of my vagina? Thank you!!
