Aggressive female during breeding?

[windswept]

Hey guys, looong time snake owner trying to get into breeding. Second season to attempt, no success yet. And I have a baffling situation I can't find any information on.

I have two males and two females (all of the sexes were 'sold to me as' and haven't been probed by me/my vet yet, and that'll be important in a second). My plan this year was to pair my BEL(m) to my spider(f), and my pinstripe(m) to my lesser(f). Pin is off feed and I felt follicles on my lesser, everyone is great age and weight so I felt ready to go and start pairing.
My spider female did this last season and is doing it again now, where she acts really aggressively immediately when the BEL (or the pin) is put in her cage. She'll shove at him, bridge her body, and act rather like two males fighting, though the BEL isn't fighting back at all and just continues to look interested in mating and tailwagging. Last year I only had her, and this led to me pulling the males early from her. She developed very clear, obvious follicles, ovulated, never laid anything. This year I put the BEL in, same problem.

The obvious first question is if my BEL and Spider were sold correctly sexed.
When I put the BEL with the pin, they both start acting like normal males, and when I put my BEL to the lesser (as they are right this moment) everything is calm and appears to be typical breeding introductions (the pin also was calm typical introduction with the lesser female). So the BEL seems to prove he is male.
When I put the pin to the spider, she acts the same aggressive way. She was sexed female by NERD, and like I said she had very clear signs last season. She's 4~years, near the 2,000 mark in weight.

I could bundle them all up and take them to the vet for the final probing, but the issue seems to be specifically with the spider and all signs point to female, save the aggression. So... has anyone been faced with a pissy female before?

I have females that get aggressive towards me (more of a crazy feeding response than aggressive), but never towards a male. I would have it resexed to make sure...

If your snake ovulated she would have laid. Or become egg bound and likely died. If they don't see a male and are building follicles they will absorb them, but not after ovulation...

Ah. Yes, I mean they were just follicles that reabsorbed then since neither of those happened (obviously). Definitely thinking about trucking them all by the vet, but alas I have to wait until my car gets out of the shop.

I have a definite female who acts that way. My mojave female. My husband wanted mojave spiders, so we agreed he could pair his spider to her alternating with my vanilla male. The trouble was, she HATED that spider male.

Every time he went into her tub, she did just as you describe. Throwing her body around, moving rapidly away from him, slamming him against the tub with her body. It was quite violent. The first time it happened, naturally we took him back out after a few minutes and let her calm down. Tried again the next day and had the same thing happen. After the second attempt with the spider, we let her calm down for a couple of hours and introduced the vanilla. She's just as sweet as you please, lifting her tail and getting all cozy, they locked in no time. So, we wait a week and try the spider again. Once again, she gets very violent and we rescue him. So, we decide the spider must not be a boy. To check, we put him in with a normal female. She started tail wagging right away and locked within a few hours.

We tried a total of six times to put the spider with the mojave before we decided it wasn't worth him getting hurt. The vanilla male sired her clutch and I even hit the double gene. The spider also fathered a nice clutch from the normal. So yes, it is possible she just doesn't like your males.

That being said, DO get the suspect snake sexed. I think cases of females refusing males are very, very rare and it is much more likely that it's another male.
