whites sexing

so last night at about 12 i hear one of my friends croaking it was the smaller one i also have one that is about double the size im guessing she is a female and the smaller one is a male. yesterday i cleaned out the setup and put some new live plants. so any ways when i heard it for the third time i turned my flash light on and looked over to see them sitting on a leaf of the bromeliad and the male was on top the female. tadpoles to come? i hope so
