every bun is different. my males are all very friendly, but they have been socialized tremendously. my holland lop the most so he is extremely tolerant but does not look for constant attention like my bigger buns.
i am also a male fan, as i have 3 males right now. but it will ve very hard to add a third male, it would be easier to just add a female. there have been instances on the forum of aggressive male rabbits and it comes down to the breeding lines and how well they are socialized young which is one reason among many you dont want a pet store bunny. find a rescue after your youngest is nuetered and take them on bunny dates to find the right girl. she will already be spayed and that way you dont have to go through the trouble of litter training also
