lop-eared rabbits and gender characteristics

Question
Hi! My question might be a little long-winded but it has a sort of important story that goes with it to make sense of what I'm asking.  here it goes:

I owned a male rabbit for eleven years, a house bunny named Dusty, no cage, litter trained. He was a mini-rex. After he passed on I decided to get a female bunny. She is a holland lop. I have read lots of bunny books but focused on one in particular when I noticed most of the information in that book seemed to contradict what I had experienced.  It stated that female bunny's do NOT spray, males do. The rabbit they used in the book was supposidly a male bunny, but he had the big furry ring around his neck, like the females have for making nests. I observed that my male bunny did NOT have a ring, my female bunny did, SHE sprayed, not him, and she is more agressive than he was.  So, I assumed the owener of the rabbit in the book simply was mistaken about the gender of their pet and mistakenly wrote an adive book about the wrong thing.  Now, a few months after getting Thistle, my female bunny ,  I bought another one, Fern, who also sprays, has a ring around her neck and is more agressive than my male had been.  However, when I let them meet for the first time, Thistle started to mate with Fern's head! At that moment I began to wonder if the book I was reading had more credibility than I first thought. Maybe male lops CAN spray and have a furry-ring! This is what I'm wondering:
Can a MALE Holland Lop bunny spray, possess a ring around it's neck, make nests and give "birth" to fake litter of stuffed animals? My female bunny Thistle, the one with gender in question has one male trait, that being rabbits tend to orient themselves to humans of the opposite gender from themselves and SHE loves women, which makes me wonder if she's a HE. Thistle isn't a holding bunny and from cuddling'on'the'floor position her fur, unlike Dusty's was, is too long to tell if she has testicles.  If it turns out that a male Lop can possess some female traits I need to know so I can get her checked, because if I don't I might end up with lots of baby 'Thistle-Ferns'.
Thank you very much.

Answer
Males and females both can spray, although it is a lot less common in females.  Males commonly spray.  Females most commonly have dewlaps, although I have seen males with them too.

And yes, I have seen a male Netherland Dwarf, who, even though he was neutered very young, still made a nest every year.

And mounting is a lot of times a dominance behavior, especially between rabbits of the same sex.  If not of the same sex, the bunny on the bottom can inflict painful damage to the other rabbit's parts.

I would recheck the buns to make sure that they are indeed both female, otherwise it may be too late to prevent babies (although a pregnant rabbit can be spayed if you aren't morally opposed to that).  You can find pictures at http://www.rabbitnetwork.org/articles/sexing.shtml

Gender doesn't seem to matter in whom they like, so I wouldn't worry about that.  But definitely check to make sure they are both of the same gender.
