Question about males and females (x posted)

[adinco]

Ok so I've got two FBT's. I'm positive one is a male but not sure on the other one. My male (Shell) chirps a lot and has mounted the other one (Camo) quite a few times. I've heard camo make a fast chirping sound and then run away from Shell. I've read that both males and unwilling females will do this when a male mounts them (whatever that's called). So my question is... there's only 2 toads in there. If they were both male would Shell still be chirping and mounting Camo? If Camo were a male wouldn't he be chirping too? Does it sound like Camo is a girl?
