thinking of trying anal

the title is self-explanatory but I honestly don't know the protocol of how to clean everything and prevent any chocolate sightings. I'm not sensitive there so I've never really tried but curiousity got the better of me and my husband has been dropping hints since the beginning of time so I tried to get used to the feeling of anything going on by using little butt plugs but honestly all that did was make me feel like I needed to poop. also I have concerns about leaking after, is this a side effect or just a bad rumour?
