I think I should assume this is not a good lock, but is it normal for virgins to be a little confused about what goes where?

Also, people post poop threads and comment about how silly some behaviors like periscoping are but TAIL WAGGING IS THE SILLIEST THING I'VE EVER SEEN! When I first paired them the female was circling around the male flicking her tail in the silliest of ways. He looked very confused about how to approach her but was definitely interested. She smacked him in the face once and it was hysterical!

They seemed to calm down a bit and the male was rubbing his chin along her back and moving very seductively around her. Last night / this morning they are sitting with their tails pushed together but the male has his vent turned up and the female's tail and vent are flat on the ground. This is why I think they are a bit confused? Will they get the hang of it and make a more obvious lock? Can he uhhh... get it in... from the side like this?
