Most of the geldings in turnout are respectful and will walk away once you've chosen a horse to halter. My friend's arab gelding, who is best friends with Aires, was being a little pushy and clingy with me but all I had to do was point and say "CJ, go away" and he wandered off and didn't bother us. Of course, most of the other geldings are worked with every day or are older and know the rules. Willie is young (I think he's maybe 4) and I have seen his owner at the barn once in the two and a half months I've boarded there. She doesn't ride him, nor does anyone else. He stands in his stall unless he's turned out. So, I'm kind of not surprised he has bad/pushy ground manners (he's even pushy in-hand).
If this type of situation arises again, I will carry that lunge whip with me when I go to get Aires.
