My neutered male gs/mal is reliable on his training at home. But if I take him somewhere else not so much (sorry comma key is not working) I thought he was well socialized as a pup he is completely fine when people come over. We walked him daily although there were a few incidents that might have made him nervous or protective. We have a lot of loose dogs here. Anyway the point boils down to he is hyper alert when outside of our area and particularly with men. I might sound like a complete dog newb here and I do know that mals are different. Can I desensitize him? Or just Keep him home.
