i had to look up on google what a butt plug was!! definitely a good idea - thanks for it. for myself i don't know if i can induce strong peristaltic motion in the colon through stimulation of the anus. however i'm willing to experiment some more with it. and certainly it could be used to desensitize the body's fear of having the anal sphincter open near other people.

hmmmn... a plan is forming: what about starting desensitisation in public toilets by using a combo of butt plug, whoopee cushion (to make some shitting/farting sounds), and spraying a bit of fart gas (yes really! you can buy it in joke shops)...for the smell effect.

plus, did you know... gay men have a lower incidence of prostate cancer than straight men?... possibly due to the stimulation their prostate glands receive.
