He needs to be neutered first. It does absolutely no good trying to have bonding sessions right now before he's neutered, and may even hurt your chances of successfully bonding them later once he's been neutered and the hormones are gone, if your doe has a bad experience with him now.
All he is now is a bundle of hormones, and all he can think about is mating. Any interaction between them now or later before neutering, will be him constantly trying to mate with her. That won't change without him getting neutered and removing hormones from the equation. And his constant attempts at humping before then, will just upset your doe and could cause a fight to break out. Which once that occurs, may ruin any future bonding attempt.
So neuter first, then wait at least 4 weeks for his hormones to settle down before starting bonding, though you may need to wait up to 6-8 weeks if he is still too hormonal at 4 weeks post neuter. Keep them seperated, but they can be kept in adjacent pens/enclosures if there is no aggression between the bars, but make sure it's secure enough that he can't get into her enclosure to harrass her, which could again lead to a fight occurring.

It's important to understand the process involved and what escalating aggression looks like, so you know when to intervene in the bonding to prevent a fight breaking out and possible serious injuries occurring.

I’d usually rather send the bunnies off to be bonded by someone who knows what they’re doing, but that’s not in the cards for us today. I did 5 days of about 12 hours per day in a 1 by 1 xpen sort of thing. Both bunnies will just ignore each other most of the time and i’ve had no grooming or...
