Hi!
We recently adopted another bun (yay). His name is Buddle and he is a neutered male dwarf lop.

We also have our first bun, a spayed female dwarf lop (Marla).

We adopted her about 18 months before this. We did a lot of research and reading about buns being much happier together if the bonding all works out.
When we first tried to bond them, we kept it going for about 7 days, 20 minutes each time in neutral space.
All he seems interested in is mounting her! She stays very subdued and doesn’t explore or play or do anything after he does it. She just lies there in that cute little loafy sort of way. We’re not sure if she enjoys it or if he forces her to stay there because the few times she has gone to move he goes right back to her! We let them out in the living room together the other day (they live in there so we don’t usually do this, but thought we’d see what would happen!) and he got her in his pen, kept her in the corner and wouldn’t seem to let her out. He was lying next to her. It seems protective but it’s still not making me feel better about it all!
They are set up in their pens right next to each other and they flop right near the bars together all day, but when we let them go on a ‘date’ he mounts and she sits there all quiet and subdued again.
He also seems to dig in front of her, and then dig on her back! I’d leave them to get on with it as I have read that’s what you should do in some places, but he mounts her head sometimes and for his own safety, I can’t leave him doing that!
Is that normal? Should she not be playing and interacting with him and the surroundings, too?
I really would like them to be friends and they seem to be very interested in being with each other when they can’t properly get to each other!
Any advice would be brill, thanks!
