What is the best way to introduce two bunnies both male (maybe)?

[Timberwolf]

So.. I started off getting a bunny. His name is now Ajay, and the lady told us he was male. (Which we are now questioning a little.) He used to be with a pair of male guinea pigs. Sadly we had to get rid of them because they made a big mess. Anyway, we felt bad for leaving him alone, because he seemed a bit sad without any other bunnies. (One is a lion head dwarf, the other might be a mini lop if it helps) So we picked out a mini lop as stated before, he is apparently a guy, which my mom agrees with. We put the new bunny in a cage we used to use for the guinea pigs. The other bunny (Ajay, the questionable gender one) roams around the room freely because he hops over his fence. So Ajay was jumping around the cage acting very aggressive and tapping his feet, and we picked him up. He gave me a pretty big scratch on my arm, and we seemed to upset him. I walked over to him and he laid down beside my leg, he was breathing pretty hard, and we had to get him to move to see if he was hurt. He ended up fine, and he seems a bit sorry that he scratched me, but he's still paying slight attention to the other bunny just more calm. My mom thinks he might be a girl, and the new one a boy. We're thinking about getting them neutered.. where should we go from here?
