Is it normal to be turned on by fire ants?

My wife love dominate me. I love it too. She comes up with some of most outgafious punishments I ever heard of. She bring me outside and stomp fireant hill in her boots. She pull me pants down and make me sit bare ass on fireants while she laughing at me. It supposed to hurt. Suppose to be punishment. But she go to work in the morning and i go outside and sit on the fireants, abd it get me hard. They crawl in my rectum but hurts a little bit when they bite up there. I dont wanna tell me wife, cause then she wont make me do it no more if she know i like it.
