Why does pooping feel so breath taking when drunk?

Why does pooping while drunk feel so amazing I almost get an orgasm, this is angelic. More so when on a 2-3 day binge, the poop slides out so easy and it feels so good I almost wanna get up from the shitter and headbang with bits dripping on the floor. Okay I understand while being high on weed, cus of the increase in sensory perception and it feels amazing, but alcohol? I never thought it would make pooping feel so good
