My boy was gelded at 4 and was very colty prior to being cut!! That was 3yrs ago now and to this day he is still very dominant when paddocked with others! He still has some stallion traits which is a big advantage in the ring**) but I have to be very careful who I put him out with as he beat the crap out of my 2yr old colt the first time I let them out together (supervised of course) with mares hes bossy but better with girls. He is now a valuable teacher to my 2yr old colt and is doing a fantastic job keeping him in line!!! I just have to watch them the times I put them together and I will not leave them out ever without being there to keep an eye on them. Gelding has had hold of colt on more than one ocassion and made him scream with pain for being pushy and not backing off with the rough play! Hence colt is very respectful to gelding now and becoming a very responsive and pleasant show colt!
