Asking this question as if it's a normal activity in your house is troubling. I do recommend seeking professional help if you'd like to get rid of this habit, or maybe call 911 to report yourself to a capable adult to force you to get help.
I'm not here to shame you or your family values, I'm just worried about people around you especially these with children.

All the best man with your journey. Hopefully it won't end up with a bullet in your brain by a hurt father after finding that you did what you fancy.
