I really thought you were going to say AI..
I know some males hate it when you try to help them,
they don't even want you in the room.
When my one male was about a year old he was like that...
But.. not anymore now he doesn't care who's around.
My other male I think he was born humping. LOL
When he was young..If you reached down to pet him..he would latch on to your arm and go to town...
Anyways, Good luck with getting your babies into good homes..
