I have a 1.5 year old intact male. He doesn't hump anything. The first time I ever caught him trying to hump my older dog, I scared the living daylights out of him, and well he paired that with humping cause he just doesn't do it.
I dont do dog parks, so I don't know how to go about that, but i'd have a long line on him to start and correct him every time he tries it.
