my rabbits hate each other

Question
i hope its not too early. after much thinking i decided to go ahead
and get the introductions and bonding started. i just want to tell
you all what happend and what you can make of it.

first off, Ryo is a spayed female, two years old. and Alex is a
nueterd male, five months old.

well, i got out my extra NIC cubes and made a small playpen. i put
it in neutral territory. i put Ryo in her carrier, and Alex in his
and placed the carriers both in the pen. i opened it up and let the
fun begain.

it started out well. i thought it was this "love at first sight" i
was hearing about. but just as i sighed in relief Ryo got ontop of
Alex and backwards mounted him, while holding onto the fur on his
neck. i read that this is normal and always happens so it didnt
worry me. Alex didnt fight the mounting much at first. He tryed to
run away shortly after and Ryo chased him. so there they were both
going in cirlces and grunting at each other. At one point Alex
grabbed a hold of her fur and yanked it out. i was shocked to see
this little bunny do this! Well Ryo decided she wouldnt have any of
that, so she lunged at him. i was scared it was going to far. so i
sprayed them in the face with the water bottle. it didnt even fase
them at all. they didnt stop to dry off, or even stop fighting.  i
had to gently push Ryo away because i was scared she was going to
hurt Alex. at one time they appeared to be fighting dangerously bad,
so i put Ryo in her carrier for maybe two mintues and let her back
out. after that she backwards mounted Alex some more, and went into
his little carrier and layed down. Alex then crawled in beside her
and layed down with her. i was relived to see this. after about five
minutes of that Alex got out and went to the other carrier to groom
himself. they didnt pay each other much attention. Alex came out of
the carrier to check out his surrounds and twice he went next to the
carrier Ryo was in, and she lunged at him, but didnt even come close
to biting him. i think she was more less "stomping" at him. After
that he went in his pet carrier, and both rabbits were just looking
at each other.

i put them both up, and moved Alex's cage right next to Ryo's. from
what i have seen they dont appear to be too interested in each
other. Alex was watching her very closely and was up close to the
bars, but he lost intrest pretty quickly.

from everything i read i say this went pretty well! am i correct?

hopfully i didnt do anything i wasnt supposed to do, and didnt
introduce them too quickly. he was just so relaxed in his
surroundings i figured i could go ahead and do it. quicker i start,
the sooner  i can finish!

Today they had another twenty minute introduction. at first it went
well. they compleatly ignored each other. id say they didnt pay each
other attention to ten mintues of more. and then Alex started
chasing Ryo. it looked like he was wanting to play. he keept trying
to get under Ryos belly. Ryo would run off and the baby would keep
harrassing her, so she would lunge at him (not attacking much, and
when she did get him there was no blood shed) and Alex would jank
out her fur. so i put a towel between them. they started to squable
after that pretty bad, so i put Ryo and Alex in there seprate
carriers. they calmed down, and i relased them again. Ryo stayed in
hers, Alex climbed in there with her, and they started fighting
again. I made a ton of noise and alex cam out. Ryo didnt chase after
him, but just layed in her carrier. Alex just explored his
surrondings and ignored Ryo after that. after a few more mintues Ryo
came out to investigate and netiher of the rabbits were being
aggressive. Ryo hoped back into her carrier, then the twenty mintues
was up, so i put them up, and i put Alex in Ryos cage and Ryo in
Alexs cage for about five mintues.
is this going bad? or good? or normal?  

Answer
I would say it's going pretty normally.  It sounds as if they are having a disagreement over which of them is going to be the dominant bunny (Ryo mounting Alex is a dominance behavior, and Alex putting his head underneath Ryo's is another dominance behavior).

I would stick with the short introductions for the time being so they can work out which is dominant.  Certainly putting them in the other's cage isn't bad, so they get used to the other rabbit's smell.  You could certainly swap them to the other's cage after each session.

Mounting is normal behavior, but if they start pulling out fur separate them for a little while.  

But so far it sounds like everything is going fairly normally.
