I masturbated in the church bathroom
I really hope you're kidding. Why would you masturbate in the church bathroom?
It's a place where I feel most safe
I don't think it's right that you masturbated in a church bathroom. You might have made other people very uncomfortable.
But I wanted to do it. Who cares about the other people?
When you're in a public place you have to respect the other people around you. It's wrong to do that in a public bathroom, because it's something that should be done in private.
