I don't know if you actually want an answer but yes they do feel it! actually both parties would feel it but the bottom would not feel it as much because they would be penetrated so they would mostly focus on that with their senses and they would be less aware of the fact that they need to go to the bathroom but a lot of the time they can tell and the top can usually feel it
I don't know but does anyone wonder, what if a uke feels like shitting while having you know? Would the seme feel it? Well whatever, I'm out. Bye~
