Merlin's right, need to pressure test the system. I asume you're filling it up with coolant when it goes down?
Female has nothing to do with it.....really.
White smoke is an indicator of internal leakage tha is burning. It it isn't going in than it is going out.
Fill the system up and let it idle in the drvieway. HAve the hood open and keeping looking around for signs of the coolant leaking. If you aren't seeing anything going to the ground, it may be burning off.
This isn't a heavy leak so you need to look in areas that are more apt to "seap" or leak slowly. The freeze or expansion plaugs are located through out the block. The block is the very most basic part of the engine. Here is a pic if it helps:
