I want to continue my bulk but I'm at school for a large part of the day and don't want to risk having to poop in public.

Drink lots of gatorade, it stops me up

.........

When I bulk I'm living from one defication to the next, but I can't use public restrooms.

shove a plug up ur ass like a banaa or a pvc pipe it will blok the shit from reaching ur asshole but u can still shit urself the shit will jus be near the base of the rectum and u can scrape it out in the shower

Is this an OCD problem?

Can I just use my buttplug? What if it falls out when I'm walking?

On a side note my thighs have gotten big and now they run together when I walk, how to soothe the irritation?

No I just get nervous about having my dick out in public (cuz tiny) and my bowels stop working

u cant use a butplug becuz it is meant to slide in nicely and easily so when the shit sprays from ur colon into ur rectal cavity the force of the shit moving nearly 4 or 5 mph, will force the buttplug fro ur asshole cavity
wear a diaper under the banaa and incase ur shit seeps out down ur leg ur diaper will catch the shit and it will soak into ur diper but it wont run down ur leg so ppl can see just spray some cologne on it

shave ur legs down until ur totaly bare (as a newborn is) and add duct tape to ur inner thigh. the 2 strnds of suct tape will rub on each other with no friction and u have no more thunder thigh rash
