Has this happened to you

So I can’t poop at my boyfriends or if he’s over (new relationship only 6 months in 😬 and in my last relationship of 2 years I never did it either)

And we spend the whole weekend together, I can last and it’s fine. But if we go drinking, it makes me need to poop even more. And we went drinking last night, he just left and I went to the toilet. And now my stomach hurts bad with cramps and turning like I just need to keep pooping
