This original poster's bunny is definitely exhibiting hormonal behaviour.
I find with my rabbits, it depends on 'how' I pick them up. If they really feel secure, they get used to it.
If I keep one hand on their bums, the other on their chests and support them by holding them against my body with their feet just kicking the air (they can't be allowed to kick anything but air), they don't feel like they're going to be dropped (or eaten), and they get used to it pretty quickly.
The big guys are a bit different, I hold the little guys largely upright sitting on my hand with their backs against my chest, but I think the big guys are more 'craddled'.
To get them used to it, I start by picking them up while I'm sitting on the floor and I release them immediately as soon as they start to struggle. I give them a tiny treat while I'm holding them or after I let them go.
Hope this helps!
