I love watching pretty girls having explosive diarrhea. When I was in high school, I would give them diarrhea on purpose.
Do you still do this?
Not anymore.
Everyone has their won sexual quirks, but what you did was harmful. You shouldn't give someone a laxative to force them to have diarrhea. You should get consent from someone before performing sexual acts on them.
It's not that big of a deal, it's not like making someone shit on purpose will kill them. I'm more into other things now.
It is a big deal, as you could've caused harm to them. It is good that you have stopped this behavior.
